Touch of the Billionaire Trilogy

When Adrian first discovered her husband's infidelity, she was at a loss.  Her first and foremost concern was her daughter, and how to care for her as a single mother.  Just when she starts to get her feet underneath her, life throws her another loop in the form of a gorgeous billionaire boss. She falls hard for the job itself, as an event planner for a non-profit foundation.  She loves the work and finds herself naturally inclined to the position she was given.  But the roller coaster named Andrew Cole was almost too much for her to handle.
Perhaps her reaction was too much for him, but then again, perhaps his actions were too much for her.  Will they manage to work it out or is it all just too much for Adrian and Andrew to handle?
