Joy by Danielle Steel

Allegra Dixon has never felt loved or wanted. Rejected by her mother - a cold, beautiful socialite - and her absentee military father, Allegra's only escape from her lonely existence is through books and her own rich fantasy world.

When she finds love with childhood sweetheart Shepherd Williams, her heart feels full for the first time. But as Shep follows in her father's footsteps, pulled into the dark world of military conflict, Allegra fears she will end up alone for a second time.

Desperate for a fresh start, Allegra moves to LA and takes a job as assistant to film score composer Henry Platt, a man with a reputation for creative genius and an intense, frenetic personality.

As new love blossoms and washes away the pain of the past, Allegra begins to find her place in the world, and a feeling of joy that no one can take away from her . . .
