Frances O'Roark Dowell's The Secret Language of Girls can relate to teenage girls around the world.
Kate and Maryiln have been best friends forever but now, things are changing. Marylin decides that Kate can act immature at times and she decides to start hanging out with girls who she thinks are more mature. Kate and Marylin go there separate ways and by doing so, they start to hang out with other kids. Through the changes they always wonder about each other. Still caring about Kate and their friendship, Marylin tries to stop what might happen to Kate when things get out of hand.
I would recommend this book because The Secret Language of Girls shows that people go in an out of your lives but there is always a true best friend that will always be there. This book also teaches that no matter what happens in a friendship, true friends always care.
