Key Witness (The Security Experts, 1)

When Elle Philips witnesses an armed robbery while standing in line at the bank, she sets into motion a deadly game of cat and mouse. Mark Denton, a security contractor and former navy SEAL, also witnesses the robbery, and is hired by Elle's father to keep his daughter safe following the incident. And while Denton's desire to protect Elle goes beyond professional bounds, he cannot let personal desires cloud his judgment—judgment he'll have to rely on when the robbers' true motives are revealed…and Elle becomes a target in the ultimate plot of revenge.
