Again, I have to thank a random reader's Listmania for pointing out Zemindar by Valerie Fitzgerald to me.
As you can tell by the cover, it is an EPIC novel, published in the 1980s. The story follows Laura Hewitt, an English spinster, who accompanies her cousin Emily (and Emily's husband, Charles, who Laura secretly loves) to India.
The three meet up with Oliver Erskine, Charles' half-brother who has lived his whole life in India. He is a "zemindar"--a hereditary ruler of a vast parcel of land. Laura and Oliver connect...and maybe fall in love.
The story takes place in 1857, right during the time of the Indian Sepoy Mutiny. Fitzgerald's attention to history is amazing. You experience the mutiny and suffer with the characters through a siege...which may be why this book is almost 800 pages long.
Anyway, nice historical read about India--I recommend it, if you're in the mood for an epic story.
