A cute middle grade novel about a Vietnamese American surfer girl named Trot who is accidentally engulfed in a big wave and cast underseas with her trusty cats. What she discovers is a fantastical palace ruled by mermaids, when her trusty kitty, Cap'n Bill, fends off some dastardly serpents, the mermaids welcome the unlikely duo. At first Trot is apprehensive about staying underwater too long, she cant leave her grandfather alone for too long and her mother is at work, but soon she is having too much fun with her new friends. That is until disaster strikes! Cap'n Trot's services will once again be needed to take care of the serpents that threaten the realm. Cute, whimsical, but not terribly action packed. It's fun and I think younger teens will be intrigued.
