Secrets of the Crown - is the second book of the series.
Prepare for the unfamiliar
When every bit of human magic disappears suddenly from Vastia, it falls on the familiars—Aldwyn the telekinetic cat, Skylar the know-it-all blue jay, and Gilbert the gullible tree frog—to find the Crown of the Snow Leopard, an ancient relic that can reverse the curse. They learn that the only way to do this is by following in the paw prints of Aldwyn’s missing father, who went searching for the Crown several years earlier. This magical spirit trail extends into the Beyond, where our heroes encounter new enemies and danger, while Aldwyn learns about his mysterious past.
