I am 40 raising a step-daughter who is now 15. Communicating these ideas in a way that will be truly heard, understood, and accepted by an adolesent is always a challenge, but I think especially so for a step-parent. Dannah has done an excellent job of communicating the logical, scientific, and the emotional reasons for sexual morality and monogamy. Equally important, her style is informative and respectful, not preachy or condesending. She speaks to the reader in the voice of a good friend offering wise counsel. The presentation of ideas is far better than I could ever have done on even my best day.As my step-daughter read this book she continuously approached me with many additional questions of her own, and would even come to me at certain points in her reading to read out loud to me sections she found amazing, interesting or questionable. This was a completely unexpected bonus, which spawned several deep mother-daughter conversations.I am so thankful for this book and I have the impulse to give it as a gift to every young woman I know! I just wish someone would write a similar book geared toward young men. Young men today are even more lost regarding moral sexuality than their female counterparts. Unfortunately, their immorality and sexual irresponsibility often does the greatest long term damage to their future marriages and families.
