Not Until Noah by Lisa Henry

Carter Westlake is on the brink of being Hollywood gold. Cast as the lead in a highly-anticipated sci-fi trilogy filming in Australia, he’s primed to be the next A-list action hero: all-American, hot as hell, and straight. The problem is, Carter can only check off two of those boxes. But that’s okay—his bisexuality can remain a secret until these movies are behind him.
Childhood educator Noah Jones has a plan. Work as a nanny for six months, make some extra cash, and move to the UK to teach. He doesn’t expect his new boss to be a Hollywood star. And he certainly isn’t prepared to fall for the guy.
One kiss sends them tumbling into a secret relationship, even though they both agree it can be nothing more than a fling. Carter needs to stay in the closet for the sake of his career, and Noah’s leaving. But when their feelings continue to grow into something deeper, Carter has a decision to make. Knowing that exposing his sexuality could cost him his career, would he rather carry on living a lie, or risk it all to stand tall in his truth?
