Blood Lines — Liz Ryan

Kerry Laraghy is the girl with everything. The daughter of a lovely, loving Irish country home, she is destined to succeed her father as a trainer of world-class racehorses. But Kerry doesn't want Ireland or horses: she wants Paris, Africa and a man who can take her far away from her inheritance.
  Brandon Lawrence, heir himself to a multinational corporation, is a loving father, husband of a glamorous wife, wealthy and secure. But under the smooth surface Brandon is secretly at war with himself.
  When they meet, the consequences are devastating for them both, and for everyone they love, for decades to come.
