The Lady and the Tiger. Taylor’s Ark, #3

Dr. Shona Taylor takes on a new assignment, and discovers a chilling reality behind a picture perfect planet.What price for paradise? Jardindor is, by most estimates, a new Eden: from the number of trees to the exact spacing of every lamppost and garden, the alien planet is perfection, a totally controlled terraformed world on the outreaches of colonized space. When Dr. Shona Taylor receives her posting as physician to the settlers on Jardindor, she packs up her family - children and medical menagerie, as well as Chirwl, the alien ottle - expecting a very serene six months. But the people of Jardindor are guarding more than their perfect world.
They're hiding a dark secret, and as Shona learns more about her new hosts and their strange fascination with animals, her new job turns into a nightmare.
