What could go wrong?

So what if Trudy doesn't fit in with her silver-spoon classmates? She's a little poorer, a little... stranger. But everything will be fine as long as they never notice.

Besides, Shelter Island is sunny, sweltering, and idyllic. She's having the time of her life on summer holiday with her upper-crust friends. But the island's smiling beaches are also a disguise.

Why are her friends so nervous when storms roll in?

Why does the staff lock all the windows at night?

And what are those looks about whenever she asks?

When her friends slip up, Trudy catches a glimpse of a legend no one wants to talk about. But surely the worldly set don't take this nonsense seriously?

The puzzle pieces say that, at night, Shelter Island has a secret. It roves the island unchecked.

But Trudy has secrets too. Will they be enough for her to defy the odds?

Get it now! Because everyone loves an underdog.
