"Stella Starflake Pearl has been expelled from the Polar Bear Explorers' Club. But that's not going to stop her and the rest of the junior explorers from embarking on another exceptionally perilous expedition. It hasn't been long since Shay was bitten by a witch wolf, but he's in danger of turning into one himself. Only an ice queen's long-lost spell book and Stella's ice princess magic has the power to break the curse. The one thing standing in their way is a treacherous monolith no explorer has ever returned from...the Black Ice Bridge. In this final, daring installment of the Polar Bear Explorers' Club series, Stella and the rest of the gang embark on their most fearsome quest yet, plagued by distrustful mermaids, screeching red devil squids, irksome trolls, and a centuries-old curse." -- Amazon.
