I love this series so much. One thing I've been itching for since the very beginning was a peek at Erica's past and how she came to be the renowned Erica Slaughter, Monster Killer, and it was so cool to finally get to see her origin story! She's exactly how I imagined she would be as a kid. I loved watching how her friendship with Aaron formed (no surprise that it began with a kick in the nuts), even though there's a definite ache in my heart, knowing the pain awaiting them both.
