Kea has been adapting to life on a planet. Sunshine and air, plants and animals... maybe even a breakthrough in her quest to solve the old mystery of Mara and the Fish Pond. But then the neighboring city of Arna ruins it all. Arna's genetic weapons have shown up in Gaudi before. Animals that kill on command. Spies wearing the skin of clones. It was plenty of reason to build the protective dome. But now the dome is surrounded by a deadly symbiosis of plants and insects, engineered to trap them inside forever. Kea's only hope is to ally with a resistance movement in the heart of Arna itself. And when a coded message appears in a simulation, that hope suddenly becomes real. The trip to Arna is a journey into a whole new mystery. A complex world of foreign culture and politics, where nearly everything is alive... and a lot of it wants to kill her. And, like a fish gliding along just beneath the surface, the secret of Mara keeps following her as she goes...
