This insightful book helps women recognize the flip side of best friends --- women who undermine instead of support their colleagues and acquaintances. Dr. Delasegga provides helpful strategies to recognize them, lessen their impact, and ultimately turn their influence into a positive life lesson. This is a must have book for women dealing with women in work and social situations.

Cheryl Dellasega's Mean Girls Grown Up makes an important contribution to the study of RA (relational aggression). In her clear and engaging book, Dellasega shows how "mean" childhood patterns can and do persist into adulthood--and how damaging they are. The author of three other books, including GirlWars, Dellasega also encourages readers to see that they needn't be victims of bullying (or continue to be bullies). Other positive points about this book are its inclusion of a good number of firsthand anecdotes and its movement beyond the usual territory of female RA studies--not only into adulthood but beyond the upper-middle-class white suburbs.
