Really good book. It's not at all like Eat, Pray,Love, which is a positive thing.
(I wrote my opinion of that memoir earlier.)
This is a straight character novel, which is a type of book I like. (One character is followed throughout her entire life and explored in-depth; other characters are explained fully but the story is not about them.) It is about a serious woman botanist in the early 19th century.
It's over 500 pages but worth the time.
