Flame of the Phoenix — N.J. Walters

Phoenix is afraid -- a first for the immortal warrior. Beautiful, forthright Tilly Ledet fires his mind and body. She's been helping Phoenix and his shape-shifting comrades in their battle against Hades, and now she is in danger and doesn't think she needs his protection.

When Phoenix shows up insisting she drop everything to go into hiding with him, Tilly balks. Phoenix is gorgeous, courageous, and convincing, and he also does something to her heart… But he's an immortal shape shifter, and she's human, not to mention they also have Hades on their trail, so giving in to the heat between them could send them both up in flames.
