Love and betrayal—does any of it matter when the world is collapsing around you?

A year after Tabby Nolan’s sister vanished from the Lake Michigan shore with her boyfriend, Liam, Tabby visits the spot where the two were last seen—and finds herself pulled into the crumbling world of Avalon.

Since his disappearance, Liam has been trapped in the mythical land, with no link to the world he knew. Now, with Tabby, their shared memories of her missing sister are all they can cling to as Avalon dies around them.

But Tabby doesn’t want to be a replacement for her sister, and her growing attraction to Liam feels like a betrayal. As Avalon fades around them, Liam and Tabby must rely on each other—or be lost with the ancient kingdom forever.
