Tales of the Frog Princess, book 9: The Frog Princess Returns
E.D. Baker2017

Two weeks after Emma's birthday, Prince Eadric -- having been turned from a frog into a human again -- is still in Greater Greensward. One day, a beautiful princess named Adara arrives at the castle in Greater Greensward for a visit, claiming to be Emma's distant cousin. But Adara has other motives that threaten Emma and Eadric's blossoming romance.

Meanwhile, something is very wrong in Greater Greensward. Crops are dying, streams are drying up, and large sections of trees in the enchanted forest are withering -- all because the Fairy Queen has disappeared. Without her, there is no peace in the magical kingdom, and dangerous foes threaten to take advantage of her absence. Only brave, tenacious Emma with her knowledge of the land can restore order . . . but first she must set out on a journey unlike any before.
