Overall the books were good the first time, kinda boring the second time. The more erotica I read the more tame this came across. I would recommend reading all of the books (partly because it's part of pop culture now), but don't buy them.
This is a short and simple book. At 200 pages there is a lot of information and ideas in it. At the same time no need to read it cover to cover. You can just flip through and see what catches your attention.
Don't bother reading the actual book, because I can summarize the entire thing up for you here: sex; fight; makeup sex; fight; makeup sex; fight; fight fight; flight; yell; pregnancy scare; panic; OMG; major fight; weep; "hi," I breathed, "hi," he whispered back; makeup sex; happily ever after. I really had high hopes for Fifty Shades Freed after liking the second book in the series so much, but alas, E.L. James disappoints.
I didn't like this book for the characters or BDSM or the romance, or even the sex; only for the story. I can't recommend this, especially if you're new to erotica; this is not the kind of book you want your first experience to be. I don't recommend this to you even if you read a lot of erotica, either, because you probably won't be able to finish it. So I guess I don't recommend it to anyone.
