Missed the Mark *Spoilers*
Format: Kindle
I was surprised by the author’s bio because at times it felt like this book was written by an adolescent imagining what filming a movie would be like. I really enjoyed certain parts of the book, especially the flashbacks to HS, the flirtatious note-writing and the botched Spanish terms of endearment. But the main feeling I had reading it was whiplash, in terms of all the back-and-forth between the MCs. Even at almost 30 years old, they both felt emotionally immature.
**Spoilers Ahead**
It was odd to me that when they finally confronted their past, it was in terms of the summer after their sophomore year of HS, rather than the big breakup when they were in college. Skipping ahead, the Paris ending felt very abrupt and out of character.
I also felt that certain side characters (Troy, Darbie, Emily, etc.) were very two-dimensional and discarded easily where it would’ve been interesting to see their reactions to the MCs’ relationship.
I can see where the author laid the groundwork for a good series, it definitely has potential. This book just missed the mark for me.

Fantastic Second Chance Romance
Format: Kindle
The only reason this book wasn’t a 5* was because Amazon doesn’t allow 4.5* and I felt like parts of the rekindling of their romance at the very end were slightly rushed. Aside from that, this book was INCREDIBLE. I fell in love with them as a couple from the beginning. Gemma’s back and forth emotional parkour was a little rough at spots with how quickly she changed from wanting nothing to do with Caitlin to wanting to take her home. BUT I loved the epilogue and the full circle moments of them together and their future. Can’t wait to read another book by this author!
