Thanks for mentioning this one, I've never heard of it. It looks interesting and it's only $2.63 on Amazon right now. DD is 2nd year 14u so I figured I'll read it myself first. Thanks for the heads up on the language and rough situations.Lady Tigers in the Concrete Jungle: How Softball and Sisterhood Saved Lives in the South Bronx.
Now, is is not a motivation or mental toughness book, but it is a great read. I wouldn't recommend it to younger players, at least 16U or mature 14U player. Lot of foul language and rough situations, but I had my DD read it to give her some perspective on how things aren't easy for everyone.
