The Light Between Oceans by M.L. Stedman

A lighthouse keeper and his wife live in isolated Western Australia. The wife longs for a child of her own, but has had two miscarriages and one stillbirth. One morning, the couple finds a small boat shipwrecked with the dead body of a man and a very alive baby girl. The couple decides to keep the baby and raise her as their own child.

This book contains a lot - the effects of war, what makes up a marriage, longing for children, lies, secrets, and jail time. The writing is simple but the themes are complex.

Make sure you have some free time when you start this book because you won't want to put it down.

Thanks for the recommendation, Rebecca! =D
