I received a copy of this title to read and review for Wicked Reads 
 4 stars. 
 At Attention is the 2nd installment in the Out of Uniform series by Annabeth Albert, but can easily be read as a standalone romance novel. If you're familiar with Annabeth Albert's writing style, then you won't be disappointed with At Attention. Easy flowing scenes, with an addictive quality to the romance, and fully developed characters. 
 Apollo is widower with two small, twin daughters. His mother is going on vacation during the summer months, and unexpectedly his best friend's brother is in need of a place to crash while he works at the same summer day camp the girls will be using. It's a win-win situation. The only issue is that Dylan has had a crush on Apollo since he hit puberty, and Apollo is still deep in mourning over the loss of his husband. Apollo sees Dylan as hands-off, as he's Dustin's kid brother and has vowed to never fall in love again. 
 Apollo is afraid all the time, channeling that into a control-freak personality, scheduling a month's time at once. Dylan is a responsible guy, but he's spontaneously always finding the fun in any situation. There's an age-gap, but the pair balances each other out nicely. 
 At Attention is sure to hit all the right notes with romance lovers. Angst of unrequited love. The heart-tugging pain of loss. The sweetness of young children wanting their dad to be happy. Mixed with doubt, fear, guilt, and need, this novel is an emotional punch to the gut... 
 I want more- can't wait to get my hands on #3. 
 Recommended to MM romance fans.
