Though this was the second book in a series, you do not have to have read the A SPY LIKE ME first.
I loved HEART OF AN ASSASSIN. The story was a fun, fast paced, exciting adventure filled with witty and clever characters. Besides, Savvy, Malcolm, and Will, I loved Malcolm and Will's family. They were so funny. And you never knew if the family was going to assassinate Savvy, teach her to become an assassin herself, or welcome her to the family.
Most of all, I enjoyed Savvy. She has a big heart, and despite the fact that she defies her mother and others in her life, she only wants to do what's right while saving those she loves.
If you love reading good mysteries or spy novels with witty characters and a good amount of romance, you'll love this story!!And this series would be the perfect Christmas gift (or whatever occasion) for those teens in your life.
