Hard as Stone by Sara Brookes

Brady thrives on saving patients in his busy emergency room, but when things don’t go according to plan, he’s unprepared for a chance encounter. There’s something familiar, and mysterious, about the downright sexy-as-hell stranger he encounters on a busy Chicago street.

In Garrett’s world, there are no coincidences. He’s been the doctor’s secret guardian for years. Driven by a burning need unknowingly stirred by Brady more than a decade ago, Garrett finally breaks his silence. He steps in to show Brady there’s more to life than rescuing those in need. Roused by their desperate passion for one another, their desire reaches an explosive breaking point.
Brady realizes one night isn’t enough, but Garrett is bound by rules he can’t change. Now Brady’s healing touch may save more than just a life-it may just save Garrett’s soul.
