The language books by Ollie Richards still remain the gold standard for me, but Ein Unvergesslicher Urlaub (An Unforgettable Vacation) by Daniela Fries, comes pretty close. It’s a B1 level tale about a young couple who goes to spend some time on a workaway program, building cabins at a farm run by a couple retirees. They hope to practice their language skills, and grow closer to each other in their relationship, but end up being involved in a mystery.
One of the workaway students, it turns out, has stolen a large sum of cash and a bundle of jewelry from the family that was good enough to host him.
It's a “Krimi” as the Germans call the subgenre of crime works that deal with police procedurals. The most famous of these in Deutschland is Tatort, which is maybe the longest-running series in German history. Here the procedure is handled by amateurs—along with an international team of computer hackers—and the story is compelling enough to keep you reading. Which is to say, that apart from its educative value, the thing keeps you entertained.
Each story is followed by a section with questions that allow one to demonstrate their comprehension of the material. Or, if you’ve forgotten something about the storyline (I sometimes take days off between readings), this section provides good incentive for a reread. After the questions, then, comes a review of vocabulary.
I’d say I knew about ninety-five percent of the words encountered, maybe more, but at times they were used in idiomatic phrases I didn’t know. Maybe it’s time for me to get back to Deutschland and do a bit of “immersive learning?” Until then, Ein Unvergesslicher Urlaub more than foots the bill.
It’s followed in the series by a slightly more advanced book—B2 level—called Umzug nach Berlin (Moving to Berlin.) I might check that out next, or, conversely, I might go back to Ollie Richards. Recommended, regardless, with cute little pictures appearing before each story.
