Everything about this story was exceptional. Tristan and Isabella are by far my favorite fictional couple. They both had a haunted past that was threatening to reemerge and tear apart what was building into an amazing relationship filled with trust and most importantly love. In addition to the amazing sex scenes, there was suspense and a twist that I didn’t see coming. But let’s talk about those sex scenes, shall we? Oh. My. Gosh! Talk about out-of-this world chemistry! The sex in this book is OFF THE CHARTS and oh so HOT and delicious! It’s edgy, steamy and intense. Oh, did I mention HOT? The sex didn’t overpower the story though, but complemented it and made it breathtaking! It has been forever since a book has consumed me, but At His Mercy did just that - controlling my life until the very last page was read – it was impossible to put it down! It’s a story that grabbed me from the very first page and consumed every waking moment. It’s superbly well-written and flows effortlessly. I am truly excited and totally in love with the start of this series and will most definitely be picking up the next installment when it releases. This book won’t be for everyone, but if you love erotic romance that includes some light BDSM, an enthralling plot and a happy ending that will leave you utterly satisfied, then pick up At His Mercy. Shelly Bell has some serious talent with her amazing storytelling ability and is an author I will be adding to my list of favorites. This story is well deserving of a five-star rating and one that I would not hesitate to recommend.
