What an unlikely group. A mystery man to lead them and a magical man who is part illusion. Then add a monster who will do no harm and two faeries, who can't stand each other. And what is a Hollow Man? This novel for 9 to 13 year-old follows Hespur, a male griffin, as he attempts to keep this strange assortment of characters together and working as a team but also as he tries to convince his reckless friend Crystabell to take this dangerous situation seriously before she does something rash-and ends up dead.
