Hey, I haven't read that book but I just had a look online. I don't really know of anything similar, myself! You could check out the "what other customers bought" on Amazon or something.
Based entirely on the fact that I think it's just a great book of poetry, I recommend Here by Wisława Szymborska, who won the Nobel prize for literature. It's short but really good.
If you can give more more ideas of poets she likes I might be able to give a better suggestion!
