Former state Sen. Jeanne Dietsch will read from her book “NH: Battleground in the Fight to Dismantle Democracy” Saturday, Feb. 17, at 11 a.m. at Toadstool Bookshop, 12 Depot St. in Peterborough

The book evolved from Dietsch discovering that a national libertarian PAC made 113 of its 235 candidate endorsements in New Hampshire, and asking why that was the case. She will take questions after the reading.

Dietsch served one term in the state Senate, and has since founded the Granite State Matters news site. Its mission is to help New Hampshire residents keep up with news that affects their lives and families. Information is available at granitestatematters.org.
