The Killmores is the second book in the Killmore series. While you could probably get most of what is going on in this book without reading the first one, I’d suggest reading the previous book to get more of a connection to the characters and more extensive background on what lead up to the events in the second book. I read them back-to-back so it was more like one long novel rather than two separate books, and it worked out pretty well.
I like that the main female character remains strong, even though she does go through a period of devastation. Her responses to the events are intense and emotional, but she maintains her edge overall. The only thing I could have done without is the conspiracy theory conversation between Aiden and his friends/teammates. Other than that, it was a great continuation of the previous book. Even though it doesn’t end in a cliffhanger, the ending does leave things open for the possibility of the series continuing.
