MUST READ!
Format: Hardcover
The First State of Being is set in 1999 during the uncertainty of Y2k. Michael Rosario doesn't have any friends, unless you count Mr. Mosley, the maintenance man in his apartment building, and his babysitter Gibby. Michael worries a lot about the future, his mom, and just about everything else. So when a mysterious teenager (Ridge) shows up near his apartment complex one day, and says he's from the future, Michael is determined to find out what's to become of the world when the year 2000 is here. Will Ridge be able to calm Michael's fears? Fans of A Rover's Story by Jasmine Warga will love this story about family, friendship, time travel, and facing one's fears. Erin Entrada Kelly's voice makes this novel a must read. It's amazing!

Relatable and H O T
Format: Kindle
This story is so well-written with excellent back stories for the main characters, the relatable religious trauma vibes, and the anxieties of trusting someone after being burned too many times. Also, the sex scenes are extremely hot without being ridiculous.

Sweet Romance
Format: Paperback
This was a sweet love story between two women who are both dealing with some baggage, and figuring out what moving forward looks like. I enjoyed both of the characters and their chemistry. Also really enjoyed the supporting characters, including the animals. Listening to the audiobook, there were some moments where I had to stop and figure out which character was narrating because the voices didn’t sound distinct enough. This only happened a few times, and probably wouldn’t have occurred if I’d been reading the physical copy. Overall, a sweet and enjoyable romance with some depth and great side characters.

Adorable!
Format: Paperback
This book was completely adorable. I loved Thea and Courtney’s story, and the background from the unlikely animal friends to Colin Firth Pride and Prejudice references. Whilst a little turbulent at times with traumatic backstories, I’m glad they got their GHEA, and I loved their journey, and secondary and tertiary characters along the way. It made me smile when I was in a place of exhaustion, so I really loved it.

Not great but not bad!
Format: Audiobook
I loved the audio and I'm so glad there were two narrators! I really loved the deconstruction rep in this book. It spoke to me in ways that felt real and authentic. I also liked the way the migraine/chronic illness was handled as well. The reason this is a 3 star to me is that I can't remember the characters names and I just finished this book. The first 50% was pretty forgettable. It was hard for me to get into that first half. The second half however, I really enjoyed! Courtney and Thea (yes I did just have to look up their names) could have used more fleshing out. Courtney's ex's threats felt like a nothing burger in the end and Courtney's running also didn't hit quite like I wish it had. The last 50% things finally get moving. These characters finally start sharing with each other and being open and vulnerable but there is still a big secret that get revealed that throws a wrench into the whole thing. Overall I did enjoy it!
