The Binding. Unexpected Magic, #1

One cursed diary will change two strangers forever... Merideth Monroe was born to a wealthy politician; luxury was her middle name. The happiest childhood, the finest schools, and landing her dream career; her future couldn't have been brighter. She didn't care that her mother wanted a different path for her; but when her mother is murdered and she appears to be next, nothing in her flawless life will matter.
Rider Bradshaw lived a carefree existence. Ex-military, he only wanted out of his family's shaded history and chose to leave the sins of their past behind. However, when a girl he's never heard of is placed in his charge by his father, protecting her becomes his obsession and keeping her safe his only reality. Can Meri and Rider use her mother's old book to figure out why someone is after them? Or will the guilty party succeed, ripping the tome away before killing them and then slithering back into the darkness.
