Transplanted

A California school vanishes behind alien walls and wakes into a universe of shifting worlds. Cut off from Earth, the people of Flowering Branches must survive with what they have: horses, gardens, hard-won skills, stubborn humor, and one another. But the towering white walls around their campus keep opening onto new lands, each with its own dangers and possibilities. Lani Verrell, Raaf Herrick, Dean Hanna Lee, and a growing team of students become explorers, negotiators, rescuers, and reluctant diplomats.
Their neighbors include telepathic plants, warrior butterflies, giant spiders, stranded aliens, prehistoric horses, volcanic refugees, and a sprawling interspecies bazaar.
