Definition of kick ass heroines according to me-Heroines/female protagonists who kick some serious ass!!
Kick ass heroines are girls who can fight for their own rights,stand up for their own causes,do not depend on others to be their saving grace in a perilous situation and have not only the strength but also the presence of mind to come out of any unpleasant situation!
Katniss from Hunger Games trilogy by Suzanne Collins
Sookie Stackhouse from Sookie Stackhouse books by Charlaine Harris
These characters feel way more better to read about than the whiny ones who are maimed and crippled enough to do nothing without the 'male help'! I love kick ass heroines!
