Absolutely charming seaside setting that just bounds off the page with thrilling chapters packed full of action as well! This book is a true testament to the meaning of family and friendships, and there wasn't a dull moment in the book. Any reader will happily got lost in the mystery and riddles along with Lily, Sam, and Jay.

A fast paced,middle grade, mystery, adventure book. It has all the essentials needed for a story set by the ocean, mystery, treasure, pirates and the dangers of the rough seas. It would make a lovely summer holiday read!

What child couldn't relate to the group of friends in this book? They were querky, quick witted, curious and at times brave. I felt some of the parental characters and scenes didn't really need to feature in this story i.e., Jay's mum's interrogation of Lily. I'm also unsure about the number of times these children escaped their houses in the middle of the night via a shimmy down the drain pipe.

I felt the story had 'A Series of Unfortunate Events' vibe, with the antagonist always lurking around in the bad situations, determined to take back a family fortune they believe is rightfully their's.

The ending was a beautiful touch and highlighted the underlying message which is resonated throughout the story - the importance of family and friendship.

I will definitely be recommending this to my more able readers in my class.

I loved this book, I think it is so impressive as a children's mystery it is next level from other books I have read in this genre. Well written, fast paced, twisty and unpredictable. I loved it and I couldn't put it down. It was totally compelling.
