Hey guys hoping for some help I read a great book series that at the time was unfinished. I knew another book was coming out soon but then 2020 hit and I forgot all about it till now. I remember it was about a prince returning to his kingdom and he's the last heir because his two older brothers are believed dead they are not (one has amnesia and is fighting for an enemy and the other is a brainwashed evil assassin) the prince gets kidnapped finds out he's the reincarnation of some hero then hooks back up with his crew and old girlfriend who always wears a blindfold. The bad guys are like chaos and the universe but they are trying to stop them by turning them good and two of them have already switched sides. There is also a boy who traveled with the prince that we find out is his from a previous life. If anyone could help I would really appreciate it thanks

update I remember one of the bad guy brother the youngest one tortured women and had captured the blindfold wife/girlfriend of the protagonist and she somehow convinced him to switch sides along with him being friends with her son. also I think there were like 4 diffent powers you could have with the magic system and one of them was healing that only women could have

also one of the covers I can remember I think has black with white lines growing around it like a prism. and for the some reason I keep thinking around strands or threads when I try to remember the name of any of the books I think there were 3 or 4 with a new one that was going to come out in 2020 I'm fairly certain I read it from Kindle unlimited though I can't find it in my history
