Simply West of Heaven — Monique Bucheger

Twelve-year-old BFFs are matchmaking geniuses. Sweet! Not long after they schemed to get Ginnie's widowed dad to fall in love with Tillie's divorced mom, Ginnie stumbled upon her late mom's journals, making life even more awesome sauce … until her dad confiscated the journals, determined to protect Ginnie from a danger he won't name. Ginnie is counting on her future sister's help to make Dad change his mind, but Tillie's not so sure the ghost of Ginnie's mom will make a good addition to their new family tree. The girls' world gets flipped upside-down when a blast from the past shows up and makes Tillie go nutburgers. Ginnie is torn between helping her best friend and what could be the answer to her deepest wish.
