I adored Late Bloomer! The writing was great, dialogue well written, the characters themselves were quirky yet believable, and it was just delightful and overall FUN. Yes, the plot is a bit implausible, but hey, I'm happy to give in to suspension of disbelief. 

There isn't a lot of outright drama other than miscommunication, although Opal and Pepper's histories do affect them greatly and lead to some of the conflict between the two, but both have pretty significant character development as the story progresses that was handled deftly.

And the cover artwork? LOVE.
