Rendezvous (Renegades #5)
Skye Jordan, Joan Swan

With a demanding new boss and a chronically ill nephew, the last thing Brooke Dempsey needs in her life is one more problem. Even if that problem is a sexy stuntman who knows exactly how she likes it. Keaton is just passing through, while Brooke is just settling in. Her nephew depends on Brooke, and her life is dedicated to getting him through this health crisis, but she’s not going to make the same mistake and part ways with Keaton before taking the chance to love him—just once.
But when Keaton pushes for a future, Brooke finds her heart torn over going after the love of a lifetime or giving her nephew a lifetime of happiness.
