A lot of ink has been spilled on the rags to riches story of Calvin Harris, real name Adam Richard Wiles, and now a full length biography has been put together on the man who has electrified crowds across the world and crafted some of the biggest radio hits of the past couple years. U.K. journalist and author Douglas Wight, who according to his biography, has written, co-written or ghosted seven different biographies, has written a new book about Calvin Harris documenting his rise from a low-level employee at a local supermarket in Dumfries, Scotland to one of the wealthiest, most in demand-global artists inside and outside the DJ booth. The book, titled Calvin Harris: The $100 Million DJ, will be made available on October 21, 2015.

The Amazon pre-order gives a summary of how the 265-page book will capture the life of Calvin Harris which now reportedly involves dating fellow mega-star musician Taylor Swift and being an underwear model for Armani.

"He's made $100 million, is the hottest DJ in the world and has worked with the pop royalty - but who is Calvin Harris? And how did he go from stacking shelves in his local supermarket to such astonishing global success? He's come a long way from making music in his bedroom in his native Dumfries but since bursting onto the music scene with 'Acceptable in the 80s' in 2007, he has broken Michael Jackson's record for most hits from one album, become the first British artist to have one billion plays on Spotify and turned hit-maker for stars like Kylie Minogue, Rihanna, Cheryl Cole and Dizzee Rascal.

This is the astonishing story of Calvin Harris's journey from struggling musician to international star, revealing what makes him tick, why he has the Midas touch, how he went from being a lanky kid with little self-confidence to a modeling deal with Armani and how he became a global megastar."
