I generally don't, for the most part, enjoy YA books and try to steer clear of them.  Too much high school, too much hormonal angst, too many feelings close to the surface. Pushing the Limits turned out to be an exception to the rule for me.  I enjoyed it enormously!  In fact, I bought and sent a Kindle copy to a friend when I found the book wasn't Lending Enabled. I have a feeling she'll enjoy the book also.  When I had only a few more chapters to read I went back to Amazon and looked to see if the author had any other books published, since I enjoyed this one so much.  It appears the answer at this time is no, but a couple are due out this year.  The book itself is well written and edited (a plus in any book these days) and the characters are well rounded.  The story line for me was fresh, and the pacing was good.  I am famous for making it to the halfway point of a book, losing interest and flipping to the end to read the last few pages and then calling it a day, never to go back and read the rest of it. Such was not the case here and I was sad to come to the end knowing I'll have to wait for the next books to be published.
