4.5 
 I like this second book much more than the first one. Kat is more mature and had new questions to answer to herself, and Hale is more serious. It looks like they're growing up :P Love the tension between them... bufff... Please, it has to happen something in the next book, anything!! *sigh* 
 The only thing I didn't understand entirely: (view spoiler)[Was uncle Eddie the whole time in Monaco or only at the very end during the Emerald Exhibition? (hide spoiler)]
