Background

Tumor necrosis factor α (TNF alpha) is an effective pro-inflammatory cytokine, which can kill and inhibit tumor cells. It is mainly produced by activated macrophages and can also be secreted by other types of cells, such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils and neuronal tissues. The members of TNF alpha family exert their cellular effect through two distinct surface receptors of the TNF receptor family, TNFR1 and TNFR2. The pleiotropic biological effects of TNF can be attributed to its ability to simultaneously activate multiple signaling pathways in cells. TNF-induced NF-κB activation promotes the growth, invasion and metastasis of cancer cells.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons. A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good. B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy. Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”?? Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer. Romance 3/5 - insta-love that was then resisted because of personal hangup’s Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward. Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.

Wow.
Format: Kindle
Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️ I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.
