This contemporary M/M romance is a slow building, delightful love story. 
 Greg is a single father with full custody of his ten-year old son, Davey. He is an architect, with a thriving business, and had been scouted for the Major leagues in baseball as a young man. He is also gay. When the story opens, Greg is at Davey's little league game, but Davey struggles at-bat. Another spectator, who happens to be an ophthalmologist, suggests getting Davey's vision checked. The prognosis, after many tests, is bleak: Davey is going blind. This shatters Greg, and Davey. 
 At a picnic, Tom meets Greg and is attracted, not only by Greg's appearance, but with the compassion and love Greg shows to his son. See, Tom was raised with everything a life of privilege offered, except parental affection. He was largely cared for by nannies, and he longs to find a loving relationship that would include children. To date, all the men Tom has dated were attracted to his money. He reaches out to Greg and they decide to try dating. 
 Witnessing the anguish Greg has for Davey's lost vision, and the loss of his fun-loving games, Tom does some research. It turns out there's some new team-style games that visually impaired kids/adults are playing. One of these is 'beep baseball' and Tom dives in to assemble local support for a league. Greg is blown away by Tom's effort to help Davey acclimate to his new blindness. In fact, he's a bit suspicious of Tom's motives. 
 All questionable motives aside, Tom really just wants to spend more time with Greg. Their fledgling relationship is tried and tested when Greg's ex-wife arrives, following years of neglect, to 'save Davey's vision' with a miracle gene therapy cure. Greg is hesitant to discount any chance of reversing Davey's blindness, but the risks clearly outweigh the potential for healing. And, Tom is there to help Greg make the hard decision. 
 Plus, Tom is great at making Davey feel like a normal kid. He's the kind of guy Davey would like to see his dad settle down with, in fact. 
 It's a slow build into the physical. Tom wants to take things slow to make sure he has real feelings for Greg, and Greg is overwhelmed with the responsibility of caring for a newly-blind child. I really appreciated the author's sensitivity in holding off, and in having Tom fully commit to a real relationship rather than jumping into bed. 
 Both characters were very well-developed and the arc of Davey's transition from poorly sighted to completely blind--and as a functional blind person--was heart-remanding and terrifyingly interesting. I loved he community that Greg and Tom shared--gay, but also some had visual or speech deficits. I haven't read the two previous books in this series, but I strongly suspect that other couples' romances had been featured. This is a gentle romance with steady growth of both protagonists into a relationship that seems likely to flourish. I really enjoyed it!
