Just bought for 2.38 euro at the Action: the Prince biography by Matt Thorne!
.

The book is translated to Dutch, and has 392 pages. I hope it is the full version, since I remember seeing the English version, and that book looked much thicker... Also, the "Action version" book does not mention the passing of Prince, so is not the updated version. Instead it ends with: "hij zal de rest van zijn leven muziek blijven maken. En wie weet hoe lang dat zal duren?".....
