Knights of Caliban: Dark Angels Omnibus - Gav Thorpe

Rescue her daughter, destroy her dragons, defeat his demons, go back to his lonely life. How hard can it be?
"I like not only to be loved, but also to be told I am loved. the realm of silence is large enough beyond the grave." George Eliot
When Susan Cunningham's daughter disappears from school, her pleasant life as a fashionable, dashing, and respectable widow is shattered. Amy is reported to be chasing a French spy up the Great North Road, and when Susan sets out in pursuit she is forced to accept help from the last person she wants: her childhood friend and adult nemesis, Gil Rutledge.
Gil Rutledge has loved Susan since she was ten and he a boy of twelve. He is determined to oblige her by rescuing her daughter. And if close proximity allows them to rekindle their old friendship, even better. He has no right to ask for more.
Gil and Susan must overcome danger, mystery, ghosts from the past, and their own pride before their journey is complete.
