LEADING technology author, Barry-born Dean Anthony Gratton, has another best-seller on his hands!

His latest book Zero to 100,000, which he co-authored with wife Sarah-Jayne Gratton, has reached number 33 in the Amazon UK best-seller charts based on pre-orders alone.

Gratton, who grew up in Trinity Street, is the only author in the world to have penned two best-selling books on Bluetooth technology.

His latest work, which comes out in October, takes a fresh perspective to using social media in promoting both small business and personal brands. US Publishers Pearson are so excited by pre-sales that they have already put plans in place for a second edition.
