For those interested in the Jodi Thomas Harmony series, “The Comforts of Home,” set in Texas, is just on the shelves. Leave Texas for a setting in Montana and read “Sage Creek,” Jill Gregory’s newest novel in large print. “The Helltown Massacre,” in the Family Jensen series by William Johnstone, will keep you out west in the crosshairs of a man trying to reap a fortune with a new railroad. There are hired killers, murders and a lynching to stop before it’s too late. “True Blue” by Diana Palmer is a continuation of the “Long, Tall Texans” series.
