When their older siblings move out, Bastián Silvano has one job: protect the secret world they’ve all shared since they were children. For years, the world under the lake has been not just a magical place; it’s been a safe space for their neurodivergent brains.

But when Lore Garcia finds their way in, everything changes. The world under the lake pulls Bastián and Lore in without warning, and makes Lore part of its landscape, fracturing the once-unshakable bond between the Silvano siblings. Soon, the mistakes Bastián will do anything not to repeat, and Lore will do anything to hide, find their way above and below the surface.

As Bastián tries to hold both of their worlds together, Lore must decide how much they’ll risk for the magic they’re now part of–and for Bastián.
