Gaurav Garg was born in Delhi. He is a Computer Applications graduate from Indira Gandhi University and has passed his higher secondary from the CBSE Board. During his under- graduate studies, he started his career as an indie game programmer, but didn't gain success because of a lack of or say, no experience. After this, he learnt that passion is not the only thing for geting success; experience matters a lot. Then he joined Isis Design Service as a game programmer, where he published a few iOS titles and one web-based game. He worked there for a year and a half. Then, he moved to Jump Games, Pune, and worked on a few good game titles such as Realsteal and Dancing with the Stars. Now, he works for Mr Manvender Shukul in Lakshya Digital Pvt ltd. and has been there since the past year.

He hasn't reviewed a book before, but one of his articles was published in Game Coder Magazine. The article was on Unity3D. You can download the article from his personal website, http://gauravgarg.com/.

Kristian Hedeholm studied Computer Science at Aarhus University and now works as a game programmer at Serious Games Interactive in Copenhagen, Denmark. Since Kristian joined the game industry back in 2009, he has worked on a couple of released casual games. In addition to this, he is also the chairman of an association called Young Game Developers, which aims to spread information about game development among children and teenagers. In the future, Kristian will use his "computer mind" to develop artificial intelligence and dynamic difficulty adjustment systems for computer games.

When Kristian isn't developing games, teaching others to develop games, or playing games himself, he thinks about them a lot!
