This was a disjointed read for me. I really enjoyed the first half of the book, all the way up until...I'll call it the phone snatch scene. Hopefully, that doesn't spoil anything for new readers. Anyway, once that happened the book took a turn for the worse and my liking dropped way down. Combining my feelings, I'd set this in the high 3 stars (3.7/3.8, maybe).
What I liked about the first half was that it actually spanned years and added some realism to a missing person's case. The characters felt really defined, especially Adele. The interactions were natural, dialogue was good, chemistry was there, and the mystery was interesting. We also got to see the lead characters develop and react to each other in new ways since they were in different emotional states each time they met due to the span of time...At this point in the book I kept reading chapter after chapter and was really pulled in.
Then...at the 60% mark, the melodrama set in. Disclaimer, be aware my tolerance for melodrama is fairly low. What I call melodrama other readers tend to enjoy so take that for what you will...Anyway, yes, melodrama...where the story goes further than it needed to while not going far enough where it should have. It'll be a spoiler if I explain more but something happens that's extreme...and then the reaction and recovery, both physically and emotionally, is just way too unrealistic...and so strange, the author describes the extent of...what happened...and within a couple of scenes we're at a love scene. It had me scratching my head.
It was also here that the lead characters started behaving in ways that I didn't think was congruent with their earlier selves and, for the rest of the book, reactions just felt off. Throw in a damsel in distress, some more drama, and a mushy ending...and, yeah, overall a really mixed bag for me.
For readers looking for a balanced mystery and romance, this book does have that...neither is neglected.
And, on a side note, for those that are interested, there's really good bisexual representation here and one of the leads is a mother so I give it points for that, too.
