Should I read “From blood and Ash”

I was wondering if anyone who read these series by Jennifer Armentrout could tell me if they are good, but without spoliers. To make things interesting you can also tell me something that will only make sense after i read it, if I decide to read it. I really wanna find something good. Right now I am reading the cruel prince series and I have just finished the 2nd book and I am stuggling to continue. I probably will continue because I wanna see what happens next, but I can’t say I was very pleased with the series.
