All The Things!!
Format: Kindle
This is definitely worth reading! The spice is nice, but the story itself is truly an epic literary treat! Tessa and her Alphas are a powerhouse force of nature who will capture your heart. This story is also a great reminder of how fickle life can be and how quickly everything can change for anyone. Every single person, billionaire to janitor, is nothing but one tragic event away from being in the same situation as Tessa was in. ❤️

Kind of difficult to get through for the first half but worth the read!
Format: Kindle
3.75/5 ⭐️ What this book lacked in being fully polished, it made up for in world and character building for sure! While the first half was hard to get through, as this is a book that starts you in the present and then goes back and forth between different times in the past to get you up to speed with what’s happening in the future (and it’s not all chronological in the past which made it even harder), once all of the book is set in the present, Tessa and her pack, Ryder, Dixon, Mac, and Tray, (and of course Josie the cat,) all begin their journeys of finding themselves both individually and within their pack which is so rewarding to see after all of the tragedy and sadness detailed in their last few years leading up to meeting. I think this book could’ve done with another beta reader or two to polish up grammatical errors as well, some of those took me out of the story for a minute to try to figure out what was trying to be communicated. Overall, this story filled with so many dichotomies of love and loss, grief and happiness, hurt and comfort, all culminating in a lovely story of a pack that strengthens each other after many tribulations, and it warms your heart so so much to see them go through every version of themselves, landing on secure and happy individuals who make a wonderful pack together. Would absolutely recommend if you like slow burn, rockstar, big city, and initially heavy and a bit dark but fades into comfort and fluffy omegaverse stories!

i should have waited for there to be reviews posted
Format: Kindle
I'm being more generous than I should because this is a debut novel i downloaded this book because i like why choose and band romances i figured that it wouldn't take too long to get back to where the prologue was because the prologue seemed to be less than a day before they met the FMC and the MMCs don't meet til 60 % of the way in which for a Romance novel kinda hard for the relationship to develop or for there to be plot beyond them just meeting in a way where the FMC really lacks agency a lot of early plot and character things are forgotten about after they met it's almost as if the last third of the book was written first and then they went back to write backstory separately but forgot there needs to be a plot i get wanting to have background on the characters, but there has to be a way to do it without constant time jumps and no plot progression. Tessa's story jumps around a week lead up so much also the band aspect is very much an afterthought in the novel Spoilers-- one of the MMCs is openly pan and one of them has been dealing with a bi awakening but being somewhat defensive about it and once Tessa arrives that gets forgotten about til the epilogue and even then doesn't actually confront his sexuality the wrap up of the church hiding her name is tied up with a quick sentence, but no real consequences for anyone i honestly thought she forgot about family pack IRS deal until the final chapter and that gets resolved in an unsatisfying way the pack is upset that Tessa gets viewed as an object and tricked into the contract but has no interest in making the company's wrongdoings public or trying to prevent this from happening to other omegas tessa goes over a lot of struggles of homelessness but she only thinks about food waste once after joining the pack -- you'd think she'd use her newfound wealth and power to help other homeless individuals, especially youths and omegas. even a little side note to say that a portion of tour proceeds or her family fortune would go towards public food pantries and shelters would've done something to connect her beginning character to the end character

BORING and too long
Format: Kindle
I could not believe how wordy and boring this book was. No spice at all. Slow burn is really a NO burn. Almost DNF and now I’m sorry I stuck with it. 500 pages could ave been 150 and it would have been more than enough. I highly doubt not recommend this work of yuck.
