Dark Inferno - The Phoenix Institute, #2

Delilah Sefton has everything she wanted: a bar to run, a home, and peace for the first time in her difficult life. Until the day she wakes up with bruises and no memory of what caused them. But when she discovers she's pregnant she's certain of two things; she wants the child and she wants to make whoever attacked her pay. Philip Drake, a former black ops CIA agent, is at loose ends, uncertain of what to do with his newfound immortality.
Then he discovers that someone has experimented with his genetic code and, worse, that they've used his childhood friend as an unwitting test subject. He's intent on protecting her and destroying them. Instead of welcoming his help, Delilah rejects him because the old wounds of his betrayal are not yet healed But she may not have a choice, as her captors will stop at nothing to steal her baby. Unless Del and Drake learn to heal the past and fight together, they'll lose their future.
