Nostalgic and Authentic
Format: Hardcover
As an adult reader, I don't read a ton of YA these days, but I love picking up one now and then that speaks to me the way so many of my favorite books did when I was of a certain wide-eyed age. This one rang true -- in the character searching for who she really is as she comes into her own, overcoming relatable anxieties and changing for the better along the way. Would gladly gift a copy to the young readers in my life -- particularly those who love music.

Nice fun read
Format: Hardcover
I feel like this is a good book to read in-between reading deeper, more thoughtful books. I enjoyed it but it could have been better if the author left out a couple of characters and added more depth to others.

Beautiful Family Contemporary
Format: Kindle
“But I believe strongly that we all have multiple versions of ourselves. And the true test of love is learning to accept all of those versions, even when it’s messy. Actually, especially when it’s messy.” I LOVE family-centric contemporary stories. They are so easy for me to get invested in and I love seeing the relationships form and evolve. I just love them so much. Here We Are Now was a really good family centric contemporary, that also really highlighted opening yourself up and conquering your fears - whatever they may be. We follow Taliah as she meets her rockstar dad Julian Oliver for the first time, when he asks her to come visit his dying father. Tal learns more about her mom, Julian, and herself than she ever expected and she has to learn to reconcile these new truths with what she’s always believed to be true. Things I Liked I really loved the flashbacks we get throughout the story. They show personality, relationships, and I love that we get to see more of Lena’s Jordanian culture. They really helped develop the characters and provide more backstory and depth. I really liked a lot of the characters! I thought Harlow was a great friend, who tried to help Taliah grow and open up about things, even if she was uncomfortable. Debra, Tal’s grandmother is so kind and insightful and warm. I also liked the moments we get to see Tal and Julian learning more about each other. These pure family moments are the ones that really shined for me and gave life to the story. I also really liked that they bonded over music! Things I Didn’t Like I have kinda mixed feelings about Taliah. I understand that Tal’s been put in this weird position and has a lot of confusing and probably conflicting feelings, but I thought she was being purposefully difficult a few times. But she did apologize for that and for being hard to get to know - and I liked that. I think overall I was just a little indifferent to her, which was unfortunate. I feel like the budding romance between Tal and Julian’s neighbor Toby, was pretty unnecessary, and mostly just took page time away that could have been used to further develop family moments. This such an easy book to get invested in. I loved seeing the family moments and Julian and Tal becoming closer, and while I would have liked more development in the family relationships, I was satisfied with what I got. Here We Are Now is a lovely story of family and discovering where you fit in. I received a copy of the book from Balzer + Bray via Edelweiss in exchange for an honest review. All quotes are taken from an ARC and are subject to change.

Ahhhh!
Format: Kindle
So I went back and read the first Dreamers Bay book again before reading this one. So very good! Melissa never disappoints! Kyle and Savanna's story is so great. It is funny, spicy, and oh so sweet and getting to revisit Devyn and Elizabeth again just makes me smile! On how I wish Ms. Brayden would revisit the girls from Soho series. Hint, hint! They were the first books I ever read from this author and they hold a special place in my heart! I have probably reread then 3 or 4 times each. It would be so great to see what Hunter, Sam, Brooklyn, Jessica, Hope and Mallory are all up to in the future. As readers we get invested in this wonderful authors characters and getting to catch up with them is like getting an early Christmas present! Buy this one - you won't regret it and if you have never read Melissa Brayden's work before you are totally missing out!!
