The two true life stories contained in Tenacity span decades-- and two worlds, Australia and Britain. Told through the painful words of mothers Julie Rose and Marilyn Cowell (as recorded by her daughters, Michelle and Sarah), this compelling read has no sugar coating as it takes you through Julie's and Marilyn's struggle to get their sons off drugs-- and the tragedies that ensue. These stories highlight the harrowing fact that addiction can happen to anyone and can strike even the best of families. Powerful and hard hitting, this must read serves as an information and education tool for both young people and parents, a lesson not to be ignored.
