The Forgotten Beasts of Eld
Young Sybel, the heiress of powerful wizards, needs the company of no-one outside her gates. In her exquisite stone mansion, she is attended by exotic, magical beasts: Riddle-master Cyrin the boar; the treasure-starved dragon Gyld; Gules the Lyon, tawny master of the Southern Deserts; Ter, the fiercely vengeful falcon; Moriah, feline Lady of the Night. Sybel only lacks the exquisite and mysterious Liralen, which continues to elude her most powerful enchantments.

But when a soldier bearing an infant arrives, Sybel discovers that the world of man and magic is full of both love and deceit―and the possibility of more power than she can possibly imagine.
