The book release is a staple of would-be presidential candidates, though Ryan has been mum about whether he'll run for president in 2016.
The Wisconsin congressman is also heading to early-voting New Hampshire in October, another move typical of a potential candidate.
Ryan isn't the only Wisconsinite to be testing the presidential waters with an upcoming book. Wisconsin Gov. Scott Walker's (R) own work, Unintimidated, is due out in November.
