My biggest problems were overwhelming roaring and too mutch porn.
Marigold and her crew is in the Void,battling enemies and trying to get back to Earth. Her crew constantly whips out their dicks and are only able to talk in short,uncomplicated sentences about her pussy,fucking,licking,tasting,fucking,fucking,fucking...you get the drill. They constantly have sex and I started to skip over all of those scenes,which resulted in very short and annoying read. Oh,and someone is roaring. Like all the times,be it Marigold herself, her harem or their enemies. Nobody is talking anymore.
I also had a huge problem of mixing up,confusing and reinventing existing religions and lores. Tartarus is not Hades realm,but a person. Greek gods are heavenly forces,but also not as archangels get mentioned, Titans are imprisoned, regular sized dudes with no powers and supposedly have logical thinking(or not,cause they still side with their kiddos),God of Heaven don't exist,just angels having disagreement and so on . I love Greek and Roman gods and their tales and I really had a problem for author borrowing names and changing facts and myths. Creativity is one thing,but if you don't want to stick to the original tales,invent your own names and gods and nobody will have problem with it.
Even ending was disappointing. I don't think it is a spoiler,if I say book ends with pages and pages of descriptive porn. Like I didn't had to suffer through enough of that already.
As a cherry,I think I should mention something that actually stood out in this book. At some point there is a sex scene where demigod can't have full access to Princess or touch her,so they have to do "dont put more than two inches in" which results in explosive orgasm for Mari. Imagine that! I think it was the only scene where I laughed out loud.
Is it worth reading this book? In my opinion no. It adds nothing to series,just makes the whole story a disappointing joke.
