Books in The Adventures of Mary Kate and Ashley series

Join Kate on an epic adventure...Starring a heroic young woman named Kate Gordon, and featuring T. A. Barron’s trademark mastery of language and setting, The Heartlight Saga collects Barron’s three beloved novels from The Adventures of Kate series into a single volume. The stories follow Kate as she travels to a distant galaxy to save the life of her astronomer grandfather in Heartlight, goes back in time to a lost Native American tribe in The Ancient One, and ultimately down to the very bottom of the sea in The Merlin Effect. Weaving together mystery, mysticism, and magic, and exploring themes of mortality, interconnectedness, and the fragility of the environment, The Heartlight Saga is a testament to the power that each of us has within us to make a difference in our world.“Bold, original . . . this book shines!”—Publishers Weekly

Mary-Kate & Ashley are spending the weekend at the 'coolest' resort ever -- The Icy Igloo Inn. It's a hotel made completely of ice -- ice walls, ice furniture, ice dishes and more. But the action really heats up when things start to melt. Someone must be behind these strange-goings on -- the temperatures are way too cold inside and out for things to just dissolve. Lucky for the guests and hotel owners, the Trenchcoat Twins are on the case!

Can the Trenchcoat Twins find out who is responsible for the monkey business at the zoo?
