The Strength of Injured Heroes

Chocolate muffin and fantasy cheer at the hospital.Hospitals are the pits – bad enough if you’re sitting by a loved one’s bedside for hours on end but even worse if you’re the victim wrapped up in starched sheets, the canula running from your arm and a catheter running from goodness knows where!

Earlier this month, I’d planned to do a speed writing weekend, rather like a delayed epilogue to Kate Eltham and the Queensland Writers Centre’s Down the Rabbit hole. I had three days to do nothing but write and I reckoned I could burn 20,000 words onto paper in that time. Easy… until my husband was rushed to hospital by ambulance.

Fortunately, his diagnosis was neither long-term nor threatening. Kidney stones are supposedly the closest a man ever gets to the pain of childbirth, but they are treatable. I spent the weekend by hubby’s bedside before and after he had an emergency operation. He returned for two more surgical stints to ensure all those noxious rocks finally met their match.

During my husband’s hospital stays, I didn’t get a lot of writing done, but we spent a lot of quality time together and I spent a lot of time reflecting about my characters, wondering how they’d react if they were forced to spend a night or two in a white walled room, sharp with antiseptic smells.

My Shahkara sees sickness very differently to most humans. After all, she gained Taloner healing abilities as a young teenager. From that time, she may have suffered pain, but her body had the natural ability to heal itself from most injuries.

At the start of my second novel, The Ghost She Killed, Shahkara has been turned human. She is no longer impervious to pain and her body cannot regenerate. She struggles to cultivate the patience to let her broken bones and bruised flesh heal naturally, believing that if she focuses on her next goal, she will heal faster.

But even in speculative fiction novels, we are not always superheroes. In fact, our favourite heroes and heroines have endearing and tenacious flaws. Shahkara’s Achilles’ heel, impatience, almost destroys her. Fortunately, more determined forces intervene, save her life and lead her on to greater challenges.

None of us know when we might have to fight against illness or other unexpected circumstances. An old Japanese saying once said, “Fall seven times, stand up eight.” A hero is forged by standing up after every time they fall. Sometimes, however, a real hero’s greatest gift is knowing when they must rest before they pull themselves back towards the quest. Maybe that’s a lesson that our heroes can teach our readers, as well.

Hunger

It drives us, feeds us. Dwells inside us. Hunger. What do we hunger for? Homer Hudson chocolate. Home-made chicken soup. Shelter, Love, Good Grades or an Amazing Job. We Hunger for Respect. Even, some of us, for Marble benchtops and Ralph Lauren gowns.

This gnawing desire makes us ache with pain or cry until our eyes bulge red, but it causes a Domino Effect. Hunger is our greatest motivator. Our saviour. Our fuel for life.

Without the instinct for food or shelter, we may not have the energy to move, nor be surrounded by walls when winter chills blow. Without our hunger for creation and achievement, we could still be unevolved homo sapiens, crouched around a campfire, watching impossible dreams burn away amidst rising smoke.

We would be nothing. Just creatures, still dominated by Desire, but the Hunger hadn’t drawn us far enough.

For Shahkara, her biological instincts are what should keep her Taloner self alive. Her never-ending, ever-driving heart-lust is both her doing and undoing. It should compel her to feed on humans and live a strong and superior physical life, but she knows that to give in to the hunger would emotionally destroy her.

Because Shahkara is half-Taloner, half-Human. The Taloner inside her is programmed to feed on Humans so as to live, exist. But her human half sees Taloner feeding as cannibalistic, horrifying, cruel. She could never bring herself to feed on one of her own. She lives in darkness from one moment to the next, wondering if she’ll ever fail herself, if she’ll ever once more give in to that temptation – like that one horrifying moment before Everything Changed. And he Died.

Life and Death. It surrounds us. Our human hearts bleed when our precious cat slinks into our bedroom with a half-dead sparrow crushed between her teeth. Cat is yearning for praise at the conquest she claimed for her tribe. Her fellow tribe members (mere mortals, Shane and I) try to remain calm as we bury the still-warm handful of feathers and flesh. Cat mews at being locked inside at night. She does not understand. Only if a cat were part-bird or part-human would she understand.

And that’s why Shahkara will always feel torn. She will spend a lifetime fighting that ever-permeating hunger, the heart-lust. Even if it means she will die decades before her time.

At least, then, she will pass from this world with a contented human conscience. After all, it’s only after we’ve slipped and stumbled and smiled through life that we realise our conscience is the most precious gift of all… Far more valuable than the hunger and desire that often drives and shapes our lives.

But, bound together, they are a formidable ally. Or burden. Whichever you choose.

Strength of a garfish

Shahkara’s talons are out-of-this-world tough. I’m not talking metal, but heavy duty titanium. As tough as the teeth of a lungfish or garfish.

A garfish, you say? Let me rewind…

When I first created my heart-devouring princess, I spent a lot of time researching her tougher-than-steel talons. They had to be strong, but flexible. After all, she ejects them from the flesh beneath her knuckles. Diamond is one of the hardest substances in the world, but I ditched the idea of diamond talons for something a little more realistic. Instead, I imagine her talons being a combination of dentine, cementum and enamel.

And why not? Recently, I heard that lungfish and garfish tooth enamel is being used as the springboard for creating a lighter material for aircrafts and other vehicles.

Queensland University of Technology (QUT) physics researcher Professor John Barry said teeth in different animals had been adapted or ‘engineered’ for various purposes in the past. “As engineering materials,” Prof Barry said, “teeth are composite materials with properties much superior to any existing synthetic composite.”

Prof Barry started studying lungfish because they are an ancient animal – he thought the lungfish tooth structure would be much simpler than modern animals that had undergone far more evolutionary changes.

“We were surprised to find the lungfish has a complex tooth microstructure – not simple at all. We are also studying garfish because they have hard-wearing teeth and we want to know how they manage that.”

Teeth are composed 95 per cent by weight of the mineral, hydroxyapatite, which on its own is very weak but when used by a living system is tough and durable.

Professor Barry is studying the tooth structure at three levels to model its strength in different situations and assess potential uses as a new material.

“The dentine’s crystals have various shapes and surface habits so I am looking at the way the crystals are arranged in different bundles and also how the tooth surface is arranged to cut, crush or grind food,” he said.

New materials of the past have have often been inspired by nature. Engineers invented fibreglass while trying to imitate the properties of wood, while velcro was based on the seed burrs that stick to clothing.

Prof Barry said copying some of the structures in teeth might lead to the creation of composites which could be used more widely in cars and aircraft, for example.

At present, carbon fibre composites are the best option available, but while they are very strong ‘along the grain’, they are very weak ‘across the grain’, making their uses limited.

“If general-use composites can be developed it will be possible to make cars and aircraft that are lighter and more fuel efficient,” Prof Barry said.

It sounds like I’m closer to finding a formula for Shahkara’s talons than ever before? But then again, maybe I don’t have to worry about composites like QUT, and just focus on the ride…
