I found this book to be even more entertaining and heart-warming than Little Women (and I loved, loved, loved that book!). Little Women, of course, is a pre-requisite to Little Men. However, my 10 year old boy read Little Men first and still absolutely fell in love with the book and all the characters. Now, he is inspired to read Little Women (something he felt sure boys would not read)
My 13 year old girl read Jo's boys (sequel to Little Men)---loved it as well!
