In A Measure of Mercy by acclaimed author Lauraine Snelling, 18-year-old Astrid Bjorklund's opportunity for formal medical study in Chicago doesn't arrive until shortly after her heartthrob Joshua Landseer returns to Blessing, North Dakota. They agree to exchange letters while she's in Chicago. And, for a time, love blossoms-until the letters from Joshua stop coming. Convinced he no longer loves her, Astrid makes an impetuous and heart-wrenching decision.
