In A Family Way: Book I of The Commitment Series

Billie Charland's life is complicated. She's a paralegal by day, an aerobic instructor in the evening, and a full time parent, so a relationship is the last thing Billie needs in a life already overly full of commitments. When a hopelessly uncoordinated new student joins her aerobics class, Billie feels a spark that puts a spring back in her step, a sparkle in her eye, and desire in her heart.
Caitlain O'Grady is a prominent anesthesiologist and ER doctor. She doesn't plan on falling, literally, for her aerobics instructor, but her efforts to get to know Billie are hampered by Billie's refusal to go out with her at night. Cat's head tells her that her heart is going to be broken again, but her heart won't let her give up on the enigmatic Ms. Charland.
As their lives become more entwined, secrets are revealed that could unravel the fragile love growing between them. Is their relationship strong enough to withstand the strain when Billie's past catches up with her? Can their love survive when they find themselves in a family way?
