Mermaid Tales #21

Sleepover at the Haunted Museum

Rate this book
Shelly and her merfriends are excited to sleep in the museum until they start to wonder if it’s haunted in this spooky Mermaid Tales adventure.

It’s almost Shelly’s birthday! She can’t wait to have her friends over and eat her grandfather’s homemade pizza. But when Pearl gets involved in the party planning, the ideas get out of hand. Soon Shelly’s small sleepover turns into an overnight extravaganza at the People Museum, complete with a scavenger hunt and scary stories!

Shelly’s not so sure about spending the night in the museum with its dark spaces and creaking exhibits. But when the day arrives, everything goes swimmingly—that is, until strange, glowing lights start to appear. Could the People Museum be haunted? Or is something fishy going on?

I enjoy reading books with mermaids in them, from simple and beautiful children books to adventurous teen mermaids and even adult retellings. :)

My daughter absolutely loves the Mermaid Tales book series, and this story is by far her favorite. A fun and exciting read filled with a mixture of both suspense and spookiness, which makes this book stand out as her most liked in the series (at least so far as we will continue to read more).

This book is perfect for early readers (second to third grade) who are looking for a nice transition from picture books to chapter books.

I highly recommend the Mermaid Tales book series.

Part of an early chapter series. Shelley has a birthday party and her friends kind of take over. Mostly discusses friendship dynamics and sea creatures.

CONTENT:
Birthday celebrations.
References to a previous party where the MC was a singer.
Gets a little scary (as the name suggests).
