No surprises for guessing which book I’m giving away this week – mine! Gemsigns is available online and in bookshops as of today, and you can win it here. First off, a reminder of what it’s about:

Humanity stands on the brink. Again.

Surviving the Syndrome meant genetically modifying almost every person on the planet. But norms and gems are different. Gems may have the superpowers that once made them valuable commodities, but they also have more than their share of the disabled, the violent and the psychotic.

After a century of servitude, freedom has come at last for the gems, and not everyone’s happy about it. The gemtechs want to turn them back into property. The godgangs want them dead. The norm majority is scared and suspicious, and doesn’t know what it wants.

Eli Walker is the scientist charged with deciding whether gems are truly human, and as extremists on both sides raise the stakes, the conflict descends into violence. He’s running out of time, and with advanced prototypes on the loose, not everyone is who or what they seem. Torn between the intrigues of ruthless executive Zavcka Klist and brilliant, badly deformed gem leader Aryel Morningstar, Eli finds himself searching for a truth that might stop a war.

Gemsigns has been called political science fiction, social science fiction, a thriller (which it definitely is) and an example of old-fashioned storytelling (which I take as a compliment). Everyone agrees that it’s about what it means to be human. But there’ll be no tricky questions about that from me this week – I just want to know why you think you should win. Post your answer in comments, or tweet it to me @scriptopus (or both!). You have until midnight on Sunday (UK time) to get it in, then I’ll pick a winner. The competition is open to you wherever you are in the world, as long as your answer is in English. Prizes will be dispatched from Jo Fletcher Books HQ in London, and remember, we’ll need your address if you win.

Here’s the question again: Why should you win a copy of Gemsigns?
