Nick Armstrong is a character in The Secret Circle trilogy.
There is some slight confusion with Nick's age. He's supposed to be one of the oldest of the group, and aged 17. However, his date of birth is given in the book as 1976, which would place him as the youngest of the group. This is likely a typo in the book and it should probably have been listed as 1975. He also has a relationship with Cassie Blake but it ends quickly due to the fact that she was soulmates with Adam Conant.
