Belfast, 1939.

When World War Two is declared, Maisie Canavan is working as a newly-qualified midwife in Belfast's Royal Maternity Hospital, helping women and babies across the community - no matter what their families' background is. She's just moved back home from London after having her heart broken, but focusing on helping new life enter the world is enough to distract her thoughts, and she's determined not to let herself fall for someone again.

But as she works more and more with Dr Alex Lowe, Maisie is pulled in by his kind grey eyes and gentle heart. Maisie and Alex find themselves drawn together - but they come from opposite sides of the Irish political divide, and the world around them isn't ready to accept love between a Catholic and a Protestant. They have no choice but to keep their feelings a secret . . .

As bombs begin to rain on Belfast, and she sees Alex risking his life to care for the whole community, Maisie can't help but wonder why two people in love should be kept apart.

Can she find the strength to go against her own community for love - or will the dangers of war mean her heart is broken for a second time . . .
