I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
Chess, the protag - doesn't ring true to call her a heroine - seems to have a boatload of problems. Had a shitty life. Has addictions. Has deep issues with herself.
And this was so prevalent, that I couldn't enjoy this book much.
It had a fairly good story line, some inventive world building, some ok mystery part - but Chess is just not a good protag for me. There is no humor, no courage, no self esteem in her. Just darkness, doubt and self-hate. And all the inner monologue doesn't help to make her more endearing - I just got impatient.
So this didn't make for an enjoyable read. At least for me.
