The exciting second installment in the award-winning Eco Warriors series will transform readers’ eco-anxiety into eco-action, inspiring a new generation of youth activists.
Fresh from their Arctic adventure of saving polar bears, eleven-year-old twins Sydney and Sierra visit a sea kelp habitat off the coast of California. While scuba diving, Sydney meets her animal contact, a sea otter named Sunny, who enlists Sydney’s help. Ocean plastic pollution has entangled another otter, and it needs to be rescued. Even if the girls are able to release the otter from its plastic prison, there’s a much greater threat in the ocean.
Together, they’ll have to use all of their wits, ingenuity, and determination to somehow help their animal friends. But as they try and fail again and again, Sydney has a sinking feeling that she’s in over her head. One thing is clear: there’s literally no time to waste.
