Thanks for letting me know!! It's so nice to get feedback from actual readers (especially when they loved it, lol). I can't believe you read it in a day - you must be fast!
The sequel is called Look Twice and it should be out this Fall. The goal is October but there have been a few technical issues so it may be a bit later. I usually post updates on my Facebook author page (m. garzon in the 'author' category) or my website (m.garzon | welcome). I haven't been on the forum much since I'm so busy writing!!
Thanks so much for recommending it to your friends, that's the best compliment ever (and may help me to achieve my dream of writing full-time).
