When I review YA books I review them first as a reader just as I do with any other book. I'll give you my opinion on characters, writing style and the plot plus I'll let you know the type of book it is, whether paranormal romance, adventure, etc. After I review the book for those things, then I will let you know how I felt about it as a parent. I may love a YA book myself, but that doesn't mean I think it should be read by all teenagers. I will always tell you what age group I feel comfortable recommending the book to.
To give you a little background on how I know the minds of teens and preteens, I have three children who are now 10, 15 and 16. My 15 year old is reading at his correct reading level, my 16 year old is reading at college level. All three enjoy different types of fiction and non-fiction. I don't consider myself an overprotective parent, but at the same time my husband and I do put limits on our teenagers when it comes to movies, television and books. Every parent knows their own kids best, so I can only make recommendations based on what I feel is appropriate.
If you ever have a question about the content of a book I've reviewed and want me to be more specific just leave me a comment or email me and I'll be happy to share more.
