beautiful story
Format: Kindle
“With Stars in Her Eyes” is a beautiful book. The characters have dealt with and are dealing with some pretty heavy issues, especially Courtney. And for Courtney especially, her past has resulted in some pretty dysfunctional thinking and behavior (quite understandably). However, while the story deals with some heavy topics, there is also a lot of humor, wonder and joy. There are so many things to love about this story — the friendship between Thea and Marshall and between Courtney and Sam; the bookshop “pets” and how they are incorporated into the story; Ms. Jeannie (who is kind of intimidating); the banter between Thea and Courtney, especially all the innuendo (intentional or not); the legal food puns; the joy and appreciation Thea experiences with her photography, especially using the older cameras and techniques she learned from her grandfather; the discussion of the books Thea and Courtney like to read; the descriptive intimate scenes; the book clubs; the lyrics of Courtney’s songs, etc.

Strong sense of place and character😍
Format: Kindle
Burke really nails emotions. I did not grow up with religious trauma, but reading about Courtney made me feel like I did. I didn't have a family that treated me like the help just because I was following my own path, but reading Thea's POV made me believe I had. It's truly a gift when an author can establish such a strong sense of place and character. I can't wait to see what she does next.😍

Ugh, why does it have to be over?!?
Format: Kindle
Okay, Amazon/Kindle is dirty for prompting a review right as you finish the book, and I’m typing this through (happy) tears right now! I have thoroughly enjoyed this whole series and have to recommend that you read each one. Moving through the stories of Elle, Darcy, Brendon, Annie, Margot & Olivia has been very fun, adventurous and satisfying overall. The romance is amazing, the steamy sections are s t e a m y, and the finales are perfect. I like that the conflicts are not too extreme, drawn out or kitschy like they can be in other forms of media. I also enjoyed that this series was written in a more modern timeline. Not to mention with a straight romance sandwiched by 2 queer romances, this series is built for bi/pansexuals. Man, I’m going to miss these characters, but I will be watching very closely for more of Alexandria Bellefleur!

A starry second chance romance that’s not to be missed.
Format: Kindle
I’ll admit I was super excited to read this and at the same time apprehensive too because I absolutely loved “Written in the Stars” and didn’t want to set it up on a pedestal of unfair expectations. Not sure I was completely successful on that front ☺️.
So Margot’s story is a second chance romance with Olivia, her high school best friend who ended up marrying the quarterback jock. 11 years later they meet and interesting things happen. Margot is one of those caustic but heart of gold characters that I’ve adored from book one. I loved there was more of that in this book and it was a nice juxtaposition to Olivia’s character that’s basically kindness and generosity personified.
Bellefleur’s writing definitely does the word “rom-com” justice, as the story is packed with plenty of pining and humor. That cat scene being the most memorable of the lot. I also loved the pacing of this book. Second chance romances often tend to yank readers back and forth between timelines, causing reading-whiplash. But in this book, there’s none of that and the story progresses with enough background to keep you engaged and focused.
That brings me to communication tropes. Love-‘em or hate-‘em they are the backbone of angst inducement. This book felt like one ginormous communication trope. Ironically, Margot’s character actually bemoans how she hates it when characters don’t communicate, which I thought was quite tongue and cheek by Bellefleur given how this book flowed.
There’s lots of sexy scenes in this book and while I loved reading them, it also felt like that’s all that was happening. Margot and Olivia weren’t really talking until the very end. So even though I liked the pacing for the majority of the book, the end was like a train hurtling down the track sans brakes. So much was happening, threads being closed with a grand gesture looming, my heart was racing and I even started reading faster which didn’t help my feeling, that it was rushing to the end.
The epilogue was great and I really loved getting glimpses of Elle and Darcy throughout this book. Overall while it may not have the tingly charm of “Written in the stars”, it is a great read that closes out the series nicely.

Very good book!
Format: Kindle
I really enjoyed reading “Count my lucky stars”. It was a great sapphic romance - sweet, funny and entertaining. It was the last book in the series and it summed up all the three couples from the series perfectly. I really liked Margot and just the way she is and also I felt for Olivia because I am similar - I usually put other needs above my own. They were just great together - they balanced each other out. Very good read.
