Now an agent for the Biota, a secret government organization devoted to fighting environmental crime, Sailor is hot on the trail of her sister, Keel, who's been kidnapped. But rescuing her won't be easy, especially if the diabolical Dr. Chenille Sarazin, has anything to say about it. Backed by Hydrus, a powerful animal trafficking ring, Sarazin has created a new device that will tip the scales in favor of poachers. It's up to Sailor, Cruz, Emmett, and Lani to stop her (with a little help from Fanchon). Can they do it in time to save the endangered animals and Keel? Find out in the second book in the EXPLORER ACADEMY VELA series.
