Summary: Castle is an observer by nature and today he noticed there’s something a bit different about the two junior detectives he’s been sort of watching. He’s going to find out what it is, even if it gets him in hot water.
Why You Should Read This: I am a serious fan of all things Sentinel so when I found this, it was awesome. So far there are nine parts in the series. Each individual story is complete though. I love Javier and Kevin’s relationship and Castle is his usual nosy self. This series is definitely worth a read.
