Valley of the Moon by Melanie Gideon

In 1975, single mother Lux Lysander is struggling to make ends meet while raising her son, Ben. One night, she escapes the chaos of her life in San Francisco and sets up camp in Sonoma Valley. But when she wakes the next morning, she finds herself mysteriously transported back in time — to 1906, to a pastoral community called Greengage that seems untouched by the modern world.

As Lux falls in love with the people of Greengage — and one man in particular — she is torn between two lives, two centuries, and two versions of herself. When the boundaries between past and present begin to blur, she must face an impossible choice between love and the life she’s always known.

Sweeping, romantic, and deeply imaginative, Valley of the Moon is a time-slip novel about second chances, self-discovery, and the enduring power of love across generations.
