His Wish, Her Command by Jo Grafford

Successful LA narcotics detective Tanya Bullock always gets her man — when it comes to cleaning crime off the streets, that is. Her work is her life, and she has no time for personal relationships or clinging to other emotional lifelines like religion. After she becomes critically injured in the line of duty, she chooses a remote dude ranch in Wyoming to take her mandatory R&R.
Unfortunately, the Broken J Ranch is also the place where co-pastor Wes Rivera of Alpha Omega Campus Ministries has chosen to escort his students on a retreat. He’s the one guy from her college days who she failed to scare away despite the three times she turned down his offer to date, and she’s certainly not in the mood for romance while nursing her wounds and mourning the tragic loss of her partner.
But Wes sees things differently. He’s always believed in living life to the fullest. And with a little help from the Big Guy Upstairs, he plans to convince Tanya she can have it all — a dose of faith, a full recovery, and him!
