Foreword, an online review service, lavishes praise on Mercy.
“Thomson creates a spectacularly creepy and suspenseful mood for the book. With so many vampire/paranormal books available, comparison to everything from Twilight to Goosebumps could be made, but Thomson avoids becoming hackneyed or trite by simply being authentic in her paranormal elements and her characters. The accomplished, award-winning Thomson has another title that will strongly entice readers.”
