Books in the The Polar Bear Explorers' Club series

It sounded like a respectable and worthy enough death for an explorer - tumbling from an ice bridge to be impaled upon a mammoth tusk - but Stella really, really didn't want that to happen, just the same. In this book, Stella Starflake Pearl and her three fellow explorers trek across the snowy Icelands and come face-to-face with frost fairies.

Suddenly disaster strikes when Stella's father, Felix, is snatched by a fearsome witch. Stella must bring her magic ice princess tiara to Witch Mountain or she will never see Felix again! But no one ever returns from Witch Mountain...Stella, Ethan, Shay, Beanie and reluctant Jungle Cat explorer, Percival, set off into the unknown.

Ice princess Stella Snowflake and her father Felix are in trouble: President Fogg has expelled them from the Polar Bear Explorers' Club, and banned them from going on any further expeditions. Stella's not going to be put off by rules and regulations though.

In this fourth explorers adventure we meet Ursula, a part mermaid girl who is determined to follow in Stella's footsteps and help her to defeat the Collector!Ursula knew the submarine wasn't designed to go this deep, but what choice did they have? No one wanted to get swallowed up by a colossal sneezing jellyfish!In a distant watery corner of the Explorers Kingdom, a submarine engineer, Ursula, is determined to become an explorer. Unfortunately, she hides an extraordinary secret, which makes her the sworn enemy of the Ocean Squid Explorers' Club were they ever to find out . . . But when The Collector threatens the Club, Ursula throws caution to the wind and leads an expedition through treacherous waters, filled with gremlins, aboard the Blowfish submarine - and joined by her friends Max, Genie and Jai - and even her idol Stella!Thrilling, heart-pounding adventure with exquisite detail throughout.
