The Polar Bear Explorers' Club
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.
Join Stella Star flake Pearl and her three fellow explorers as they trek across the snowy Iceland's and come face-to-face with frost fairies, snow queens, outlaw hideouts, unicorns, pygmy dinosaurs and carnivorous cabbages . . .
When Stella and three other junior explorers get separated from their expedition can they cross the frozen wilderness and live to tell the tale?

Explorers on Witch Mountain
The second title in this gorgeously imaginative middle grade fantasy adventure series combining the best of Peter Pan, Lemony Snicket, Northern Lights and Alice in Wonderland. Stella Star flake Pearl is eagerly anticipating her next expedition. 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, Gideon, set off into the unknown. They will face chomping pumpkin patches, vampire trolls, poisonous rabbits, outraged vultures and deranged broomsticks in their quest to rescue Felix.

Explorers on Black Ice Bridge
In the third magical Stella Star flake adventure the explorers meet gargoyles, sea-gremlins, mermaids, red devil squids - even a Gentleman Flamingo!
Ice princess Stella Star flake 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. She knows her friend Shay is in danger of turning into a witch wolf himself, since receiving a deadly bite on their last adventure. It's vital that Stella and her friends set out to find the spell book that could save his life, even if it means travelling over the cursed Black Ice Bridge.

The Ocean Squid Explorers' Club
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!
