“Evocative settings, ingenious plotting, sly humor, and shivery suspense render this sequel an unmitigated delight.” —Kirkus Reviews (starred review)
There's a storm brewing over Eerie-on-Sea, and the fisherfolk say a monster is the cause. Someone has woken the ancient Gargantis, who sleeps in the watery caves beneath this spooky seaside town where legends have a habit of coming to life. Gargantis is looking for something: a treasure stolen from her underwater lair. And it just might be in the Lost-and-Foundery at the Grand Nautilus Hotel, in the care of one Herbert Lemon, Lost-and-Founder. With the help of the daring Violet Parma, ever reliable Herbie will do his best to figure out what Gargantis wants and who stole her treasure in the first place. In a town full of suspicious, secretive characters, it could be anyone!
