“Best book I have read in awhile. I read at least one book a week. I finished this book in an evening. Simply could not put it down. Very well written. Not too convoluted. Just enough characters to follow easily. Highly recommend!! Summer cannot come soon enough for Book 2!!”

“Fast paced, short read with some good action and a relationship as the backbone. Would love to have more background on the characters and I hope to learn more about Weston and Isabella in book two.”

The dialogue which Coll uses between Weston and Isabella at the start of the book had me gripped, it was so well-delivered and realised and simmered with hidden emotion. The book is well-paced, ending on a cliffhanger with the next in the series being released later this year. It left me wanting to know more, as little threads of plot were teased out from the narrative all the way through but not necessarily tied off. I can only hope that this was done with a view to tying them all together as the series progresses.
I, for one, would like to read more and will be looking out for when the next book in the series is out.

6:17pm. Track Six. Ten years from today. No Matter What. That was the promise. When duty pulled them apart and love wasn’t enough to make either of them stay, Weston Parker and Isabella Middleton made a pact. Ten years later, a devastating bombing, an unexplainable patient, and a hidden conspiracy will bring them back together — at exactly the moment the city needs them most.
