already hooked on this - it does remind me a bit of Sekret, which I read a few books ago, but I expected that. I also expected differences - beyond even the obvious, like a US setting this time, not a Russian one - and certainly the style of the book is completely opposite from Sekret. it is interesting that young Jake here has Russian ancestry...didn’t see that link to Sekret coming. another difference is that although Jake in Tunnel Vision is being forced to work for his country’s government without the option to say no, as was Yulia in the other book, he has been left with more of his real life - school, living at home, etc. - intact. so far.
