The Other Side of the Island - Allegra Goodman
After the floods, Earth Mother created sheltered environments on the islands that remained. Honor’s family is relocated to Island 365 in the Tranquil Sea. The island has been enclosed with a barrier that is supposed to protect against wind and rain. The light is placed in the sky by a projector - a different color to represent every hour.

Honor and her family don’t fit in. Her parents stay out past curfew, they don’t teach her things other people on Island 365 know - they didn’t even name her right.

Eventually Honor meets Helix, a kind boy her age. After their parents disappear, they begin to realize that Island 365 has a terrible secret and together they begin the process of uncovering the truth.

Allegra Goodman has created an interesting addition to the post apocalyptic genre. You’ll be hoping for a sequel as soon as you get to the end of THE OTHER SIDE OF THE ISLAND.
