The Lion of England - The Lions, #1

Leaving her job at a safari park, Crissie Williams comes face-to-face with a lion. So not the way she expected to die. After witnessing his parents' disastrous marriage Alastair, Lord Winsley, has vowed never to let love into his life, but he needs a bride and an heir. When he rescues a waitress from the jaws of a lion, he finds a woman who fills his criteria, but the gorgeous Crissie proves more than he can handle.
She wants the one thing he won't give her-love. Crissie wants no more drama in her life, so Alastair's cold-blooded proposal suits her fine. One problem-she's falling in love with the gorgeous aristocrat who sees everything in black and white. Crissie, an artist to the tips of her toes, prefers colour. When he discovers the scandal staining her past, Alastair realizes that she is far from a convenient bride, but by then it's too late.
He already loves her.
