I liked it. The book is written in two POVs (Jordan and Courtney) with interesting time changing scheme. 
 Usually in plots we have problems which lead to actions which lead to problem solutions. Well in "Two way street" you would find problems, but not solutions. Because this book is about reaching the point where characters decide to start dealing with their issues instead of ignoring them. 
 The characters were so silly in attempt to show each other indifference. And I don't know how Courtney head didn't explode from second guessing every small thing. 
 I also think that their behavior didn't match with their age. They could be more mature in seventeen. The language and phrases they use is strange (do young people really talk like that?). But if you would treat this book as a parody or irony on modern teenagers than it will be pretty fun read.
