Her Billionaire Best Friend: A Sweet, Best Friend, Undercover Agent Romance (The Black Tie Billionaires #4)
Jo Grafford
Titus soon finds himself caught up in the ongoing feud between two powerful billionaire dynasties, both of whom he’s trying to protect from a silent enemy seeking to topple their empires — all the while juggling his feelings for the woman whose heart he swore to protect by keeping his distance. It doesn’t help that his latest assignment has him working alongside her to guard the newest ward of the Maddox clan, a man with a puzzling diagnosis who requires constant medical attention.
Although Titus decides it’s best for both their sakes to keep Jolene firmly in the friend category, it’s getting harder each day to ignore their growing attraction.
