Deep Dark (The DeLucas Book 3)
Isabelle DeLuca can handle pretty much anything. She's a co-owner of DeLuca Construction and is raising a five-year-old all by herself. Her daughter is the most important thing in her life, but her friends and family have no idea who the father is-and Izzy's not telling. Who is the mystery man who left her alone, pregnant, and forced to raise their child by herself? Why won't she tell?
While looking into a lead on a business associate, she stumbles across something bigger and more dangerous than anyone expected. She soon finds herself embroiled in a Homeland Security investigation and a possible domestic terrorism event. Who knew book-keeping could be so hazardous? The sudden appearance of a ghost from her past has Izzy second-guessing everything she thought she knew about life, love, and her-and her daughter's-future.
