Well written, but...
Loved the story line and the author has a good writing style. Listened to this as an audiobook during a family driving trip.
Be aware that the sexuality rating does not even mention "scenes" where a male character and female character are in a virtual reality simulation but have switched genders in their characters. The author decided to spend a couple sentences with the one character mentioning how they could grope themselves. (Definitely a gratuitous inclusion... not needed for the story or character development.)
Another "scene" pertains to a male character having memories pulled from his brain and the author spent a minute or so describing his daydream/fantasy of a female character having her uniform fall off in front of him. Even my 15 year old son was so uncomfortable he skipped the audiobook to the end of that segment. Once again, this was truly gratuitous. Same painful embarrassing kinds of memories could have been accomplished with something non-sexually related.
So, well written book, just be aware of the above and decide whether it is for your child/children.
