Mimi adores her wild, fun, full-of-life gran. Then Gran starts forgetting things. Suddenly there are cracks appearing all around their home - and a mysterious black crow - both of which only Mimi seems able to see. Mimi is determined to solve the mystery. Luckily she has new friends to help: Titch and Nusrat. Together, they're the Stickleback Catchers: solvers of puzzles and seekers of adventure. Down by the river, where the gang meet and the silvery sticklebacks swim, they discover a mysterious stone, speckled with stars. But this is no ordinary stone: it's the doorway to another world, a world of talking crows and secrets, magical constellations and memories - and maybe, just maybe, Mimi's chance to bring back Gran forever...

"A charming tale of found families and mermaids, with my favourite kind of hero at its heart" - Elle McNicoll, award-winning author of A Kind of Spark A stunning literary adventure from an incredible debut talent, perfect for fans of Kiran Millwood Hargrave, Cerrie Burnell and Katherine Rundell. I was Haven Point's first Wreckling, but I certainly wasn't the last. There are forty-two of us now, not including the mermaids. When you're a Wreckling, you mainly spend your days squabbling, eating and planning adventures. Oh, and Wrecklings also carry out wreckings, which is how we got our name . . . Washed up as a baby beside a remote lighthouse and raised by a mermaid, Alpha Lux was the first foundling at Haven Point. Now the lighthouse is a ramshackle home for any disabled person who needs somewhere to belong. Looting from passing ships to make a living, they call themselves the Wrecklings, and for the children of Haven Point life is spent adventuring on the wild shore (and getting into trouble with the grown-ups). But when Alpha spots a strange light up on the headland, she realizes that her beloved family are in danger of being discovered by Outsiders. With their home under threat, the Wrecklings must decide what kind of future they want . . . and what they're willing to do to get it.
