Background

Folate receptor 4 (FR4), also known as folate receptor delta or IZUMO1R, is a protein encoded by the FOLR4 gene in humans. It is a subtype of the receptor for the vitamin folic acid and is primarily expressed on CD4 T lymphocytes, with lower expression on CD8 T cells. FR4 is highly expressed in regulatory T cells (Tregs) and is also found in tumor-associated macrophages (TAMs) and T follicular helper cells (TFH cells). This protein plays a role in immune regulation, as its high expression can distinguish Tregs from other T cells. Additionally, FR4 is involved in the high-affinity binding and transport of folate and folate analogs across the cell membrane.

This is amazing fast pace read that is full of plot twists and lies that keep getting bad. This is a story we’re a omega has been lied to by her mother and finds out that someone is slowing dieing. 3 alpha take the omega and feed her more lies so they can use her against her father so they can find their mate Kelly. This is a dark read and ends in a cliffhanger and so good.

Ends in a cliffhanger
Format: Kindle
Thankfully, the next book is already available. Roxy Collins is the queen of omegaverse slow burn. This particular series is omegaverse with wolf shifters. Thoroughly enjoyed this book! Lots of suspense and trying to figure out what is true and what's really going on. I loved it! Pretty spicy once the action starts. Heats are pretty much always spicy. There is a little bit of male interaction, but not full-on shmex. Definitely recommend.

Epic!!!!
Format: Kindle
Absolutely addicted from the first page. The twists and turns, world building and character development all come together for the perfect Omegaverse. And let's not forget that spice because knots are life and these are spectacular. Running for book #2 because that cliffhanger was torturous.
