I won this book as a FirstRead. 
 When the main character (who remains unnamed) receives an invoice for 5,700,000 kronor, he assumes that it is either a fake or a mistake. However, when he receives a follow up notice and calls the number on the invoice, he discovers that governments around the world have come up with a system to bill everyone for the happiness they have experienced in their life. The main character is single, works part time in a video store, and has a small social circle. Reflecting on his life, he observes that he could have accomplished so much more with his life and wonders why his bill is so high. He keeps calling Maud, a customer service representative with the agency who sent the invoices, and rather than getting his bill reduced, it gets even higher! 
 This was an amusing book and a unique idea for a story. While a comedy, it also makes you think about the way you perceive the events of your life. The main character is happy with the simple things in life instead of striving for more.
