Thankful for My Fake Girlfriend by Shaw Hart

As Derek Reid’s assistant, Annie Lanin is used to his outrageous demands.
Work the same crazy hours that he does?
No problem.
Remember birthdays and pick out gifts for his relatives every year?
Piece of cake.
Pretend to be his long-term girlfriend and spend Thanksgiving with his family?
He must be out of his mind.
Derek is sure this will be painless for everyone involved; Annie just hopes she can remember this is all supposed to be pretend.
