Well, well... It's been ages since I've wrote any kind of review. So I am a little rusty but let's try this anyway. 
 So, I decided to read Shades of Treason because I really like Sandy Williams's The Shadow Reader series. It's a great urban fantasy book with very good love triangle. Naturally, when I heard that she wrote a Science Fiction I knew I have to read it. 
 Shades of Treason has a nonstop action. The plot keeps you engaged and you can't stop at the end of a chapter because the need to know what will happen next is bigger than sleepiness. 
 The book is heavy on the romance side. And I liked this romance. No love triangle in this one. Ash and Rykus had tension, chemistry, longing and fun banter going on. 
 Now on the negative side. Worldbuilding was lacking. Sandy Williams created this great universe and didn't explain anything about it. The book contains so many unfamiliar words and names. And there is not even a glossary. Okay, I can deal with the terminology, but there were also missing huge pieces of history. Who are these anomalies? Are they born that way or is it the training? What can telepaths do? How strong in their influence? What happened with Rykus? Why was there a funeral for him and how he came back? So many questions. This surprises me because in Shadow Reader the worldbuilding was superb. Maybe author kept it all for the future instalments, but I felt lost and disorientated reading this book. 
 I will give the next book a go to see if the worldbuilding will improve. But it's the only chance I am willing to give when there are so much better books to choose from.
