This book gets two stars because against all odds, I actually read the whole thing. But don't let that fool you. It's really, really not good.
It reads like fan fiction, but not in a good way. It's really rambly and meandering and indulgent with a lot of superfluous scenes and awkward dialogue that serve no purpose to the story. There's a really gross m/f sex scene, as well as a really bizarre m/m sex scene between the MC and a different character. Once the MC's get together, it's just porn. Disappointing because after you've been reading for a bazillion years, you want romance, not porn.
It's just poorly written and if it were something you stumbled across on AO3, maybe it would be alright but no one should be paying money for this.
