4 books in 1.
Although this box set includes books 1-4 the prequel to Knox and Mica's story is amiss. For the whole effect you need to read that first.
If I'm honest I thought the prequel was too short and not enough to get your teeth into, and I didn't like Knox's character in book 1...but...reading on, with the heartbreak, lies, loss, betrayals, devastation, and the hard curves of life, things made a lot more sense.
On the whole it was a good storyline, action, suspense, twists and turns, drama, romance, (plenty of sex scenes,) hope, grief, family and love. At times it came across as mechanically written and rushed. Each book was quite short, which finished on a cliffhanger...pointless when one whole book would suffice...I'd have been pulling my hair out and cussing had I bought them separately. As it was, the box set was free. Finished at 68% for the first book in the Edge of Heat series to proceed.
Not a bad read if you can get all the books together. Free is an added bonus.
