Connection is everything. If we, as readers, are going to care about the characters then we must have some sort of attachment to them.
75% finished with No Turning Back and I can finally say that I am feeling a connection with Syleen. Growing up on the streets, using rags as clothing, and digging through dumpsters to find food have all forced independence onto the main character of this novel. This independence came with the price of losing all trust in humanity. And perhaps, we as readers vs. characters haven't ever made it to that extreme, but we all know what it's like to lost trust in someone. A dear friend, a lover, a relative. The moment when you realize that depending on them is worse than toughing it out alone.
As Syleen struggles with these trust issues, I can see the human emotion coming through and I can feel the attachment to her. A little late in the book for the establishment of this connection, but I'm glad that Sharon T. Rose focused on how we, as the reader, want to feel toward the main character.
