Between was a really sweet and emotional book and Hell Transporter picks up where Between left off. I love Lindsey and Aiden's relationship. It's such a change from other books because these two actually TALK about their problems. They don't let the bad guys get between them because they take the chance and communicate. They have a real relationship so there is no wasted time dealing with miscommunications, rather they deal with the real problem - the Hell transporter who has shown up.
Hell Transporter has more action and less emotional tension. I really like the changes in the characters realtionships. This is a series that embraces more traditional values but in a realistic way that keeps the characters true to who they are. If I had one annoyance it was that I thought Aiden and Lindsey were really slow figuring out who was the Hell Transporter, as it was obvious from the beginning, but I love these characters so I'm willing to let that one little thing slide.
All in all, a great sequel with an ending that left me smiling.
