Liar Game desperately wants to be the new Death Note, with a little Kaiji thrown in. It has a strong enough hook: people are selected to be players in the Liar Game where they can win and lose great amounts of money. The Liar game is about using your wits, understanding rules and scope, and well... lying. The female lead is a normal school girl who is unwilling made a player in this liar game. Her problem being that she is simply too trusting. She is easily and instantly tricked at the start of the first round, and her only hope is the recently released convict who pulled off a scam on an MLM company.
Liar Game is an easy read, and enjoyable if you like plot focused stories, but it is nothing dazzling. If you're bored with time to spare then I'd recommend it.
