The Grimsdon trilogy, signed by the author, Deborah Abela

The idea for Grimsdon began when I became cranky about inaction to climate change. In the first novel, Grimsdon, kids live in a flooded city with sea monsters, flying machines and brilliant inventions. When readers harassed me for more, I wrote New City. After more kid harassment came Final Storm. It includes some of the amazing things that people are doing to combat climate change and help the planet.
