11 year-old Fidelia Quail, bereft from the death of her parents for which she blames herself, is captured by a pirate, Merrick the Monstrous, in order to help him reclaim his treasure which is buried in a cave at the bottom of the sea.
Eager does a great job with the main characters. Fidelia is a curious, inventive, persistent, and confident girl. She takes some major emotional knocks but keeps going. Her parents’ passion was marine biology and Fidelia shares that with them but adds her prowess at invention to aid the study of the underwater world. Her “water-eaters” should give her the ability to stay under water long enough to get Merrick’s treasure, if only they’d work. Merrick is more than just a arrrr-spouting pirate: he has an interestingly complicated backstory and fatalistic view on his future. There’s more even to Fidelia’s guardian, Aunt Julia, than the stereotypical librarian she presents to the world.
I found the setting a little confusing. It seems to be in the Caribbean in a vaguely Victorian steampunky era, but all main characters are white and some of the technology that Fidelia is working with seems supermodern.
What I really liked about this book is that it defies expectations. I spent a good chunk of the novel assuming that Fidelia parents weren’t really dead but guess what (sorry, spoiler) they are! There is a genuine sense of loss in this story that is rare for middle grade novels as everything is not alright in the end, just like life.</span
Middle graders looking for a pirate adventure might be surprised by some of the twists, but will be rewarded by the story of a feisty girl who overcomes many obstacles.
