The Lady and the Unicorn by Iris Johansen

Janna Cannon scaled the high walls of Rafe Santine's private estate, afraid

of nothing and determined to appeal to the powerful man who could save her

beloved animal preserve. She bewitched his guard dogs, then cast a spell of

enchantment over him as well. Janna's profound grace, her caring nature, made

the tough and proud Rafe grow mercurial in her presence. She offered him a gift

he'd never risked reaching out for before--but could he trust his own emotions

enough to open himself to love?
