Thorns of Revenge — Janelle Evans

More than a year may have passed, but some wounds need more than time to heal -- they need revenge… 
Hiding her heart behind a wall of indifference, Rory keeps everyone at arm's length. She struggles with Jake's return to Pinedale, but finds herself roped into being his Hippotherapist. Cruel notes and “roses of death” begin to appear, adding to Rory's frustration. The notes are unsigned but they must be from Jake, his anger evident whenever they are together. But is he the only one bitter about the past? Rory better figure it out soon -- revenge is already lurking at her door.
