The Invisible Tower by Nils Johnson-Shelton

4.0

Artie Kingfisher is looking for a special video game controller to help his sister Kay win a video game tournament. He checks out a quirky shop called The Invisible Tower, where he meets the wizard Merlin and plunges into an Arthurian quest, which turns out to be very familiar, from the video game "Otherworld" that Artie has spent countless hours mastering. It seems that the adopted Artie is the sort-of-cloned "brother" of King Arthur, and his involvement has been well planned. His first job is to get Excalibur and then free Merlin from the (actually invisible) tower, where he's been held captive for nearly a thousand years. Along with his eager sister, Artie rises to the challenge.

Funny, fast-moving and a great mix of modern technology and legend. I really enjoyed the sibling dynamics and Otherworld characters.

Warning: severe cliffhanger ending, but the sequel, The Seven Swords, came out in January 2013.
