I’ll admit, I had been worried about Travis for a while. Timeless was a total mess and the less said about Hollow, the better. So it’s safe to say I entered this installment in the AO series with trepidation. After completing this book, I am happy to say that Travis is back in top form. I will say that Frank and Riley have felt further and further away from being main characters and that didn’t really change in this entry, but that’s just me splitting hairs. If you’re enjoyed the series until now, you’ll enjoy this one. If you’ve began to fall off the series and are unsure whether or not you want to continue, this one might very well get you hooked again, as it did with me.
