Tormented rock star Liam O'Reilly left Dublin and achieved success, hoping to build a new life, free from the demons of his past. Now that seems he's got everything he ever wanted, why isn't he happy? Is it because he's realized that the most important thing in his life is the promise that he never kept?

Sensitive and damaged Rain O'Donovan lives with her brother and his friends in a tiny seaside town north of Dublin. Once a popular and lively schoolteacher, a car accident has wrecked her life, so that her only pleasure is walking in the rain, and her world revolves around mundane tasks, devoid of hope for the future. The amnesia around the time of the accident that changed everything means that her struggle with life is a day-to-day torture, and, more than anything else, she longs for answers.

When Liam returns to his home town after his two-year absence, he's determined to try to make amends for the terrible mistakes he made. But is it too late to put things right?

Rainy Days is a complete standalone and a part of the Four Days Series.
