Does Mt. Kisco have a bookstore?

Sadly no, but a short drive to Pleasantville will surprise with one, right across from Jacob Burns Film Center.

If you want Children's Books go to Little Joe's Books in Katonah at the Train Station. www.nokajoes.com 914.232.7278

As someone who once frequented Borders it's a shame that they had to leave, because it's the only bookstore that I know of in that area.

The closing of the Borders here has left a vacuum. I am yet to find a bookstore in the immediate vicinity. There's a small independent book store in Pleasantville and one of the chains is in Cortlandt.
