Boomerang expands on the themes discussed in his previous book,
The Big Short, and is based on the articles Lewis wrote for
Vanity Fair magazine. While
The Big Short focused on events in the United States,
Boomerang emphasized the global consequences of the
2008 financial crisis, with sections on the
Greek government-debt crisis,
2008–2011 Icelandic financial crisis and the
Post-2008 Irish economic downturn. Lewis revisited his interviews with hedge fund manager
Kyle Bass, which were omitted from
The Big Short due to Bass's focus on the possible global consequences of sovereign debt defaults. Bass's predictions were later proved mostly accurate. ==Reception==
