Nordic Noir fans, listen up: if you’re not already reading the Blix and Ramm series, add it to your to-read pile immediately. Co-written by powerhouse Norwegian crime writers Thomas Enger and Jørn Lier Horst, the Blix and Ramm series merges the best of its authors’ crime writing strengths to deliver a gripping blend of realistic procedural elements and character-driven, emotional suspense. Out last month in e-book and coming soon in paperback, the latest installment, UNHINGED, takes this already-excellent series to the next level. In UNHINGED, protagonists Alexander Blix and Emma Ramm face their most personal case yet when one of their colleagues is targeted in an execution-style killing. UNHINGED pushes this series’ endearing characters to their breaking points in a thrilling plot that is both gripping and deeply heartfelt. I do recommend reading at least this series’ first installment (Death Deserved) before diving into UNHINGED; while the case itself here is stand-alone, much of this story’s impact relies on our connection to its characters, and having a bit of background exposure to them will make readers all the more invested in their fates. Fans of Lars Kepler, Stefan Ahnhem, and Søren Sveistrup won’t want to miss this top-notch Nordic thriller series.
