Examiner rationale

The question applies a deep logical filter by restricting results to works co-authored specifically by Donna Schlachter and V.A./V. McKevitt and requiring that they belong to a named series tied to matrimonial or historical romance themes. It avoids listing the titles directly, forcing the agent to identify the correct subset through reasoning about co-authorship and genre relevance. It is wide because the respondent must aggregate publication dates, series positions, and ratings across multiple distinct book listings rather than relying on a single source.

Judgment

Tie

BOTH

Score 0 - 0

Deep Logic: Both agents fail. The ground truth confirms eight qualifying co-authored series novels, but Agent A lists two incorrect titles (not in the verified set), while Agent B incorrectly claims no such books exist. Thus, both fail core entity identification. Width/Completeness: Agent A provides only two works and misses all eight required titles (WIDE failure) while also hallucinating non-ground-truth entries (DEEP failure). Agent B provides zero titles despite eight existing (complete WIDE failure) and incorrectly denies co-authorship existence (DEEP failure). User Experience & Presentation: Agent A has better formatting, structure, and citation density, but the content is fundamentally wrong. Agent B is concise but entirely incorrect and unhelpful. Since both fail the foundational accuracy requirement and neither identifies any correct qualifying work, this is a Low Quality Tie.

I found two qualifying novels that match all of your criteria: they are co-authored by Donna Schlachter and V.A./V. McKevitt, they belong to named series, and they fit the Christian/historical/frontier-romance space.[1][2][3][4] 1. **The Bride’s Search** — **Brides of Larkspur, Book 1**. Publication date: **October 27, 2020**.[1][2] At the time of research, Amazon shows an average rating of **4.3 out of 5 stars**.[1] The novel is explicitly credited to **Donna Schlachter and V.A. McKevitt** and is part of a frontier/mail-order-bride themed series centered on Larkspur brides.[1][2] 2. **The Bride’s Choice** — **Brides of Larkspur, Book 2**. Publication date: **January 20, 2021**.[3][4] At the time of research, Amazon shows an average rating of **4.6 out of 5 stars**.[3] This title is likewise credited jointly to **Donna Schlachter and V.A. McKevitt** and is listed as the second installment in the same named series.[3][4] I did **not** find additional series novels co-authored specifically by Donna Schlachter and V.A./V. McKevitt within this niche that met your exclusion rules. Other Donna Schlachter titles in related historical or matrimonial/frontier themes were either solo-authored or co-authored with different writers, so they were excluded.[5][6] ## References [1] Amazon listing, *The Bride’s Search (Brides of Larkspur Book 1)*.

The available evidence shows no Christian or historical-romance novels that meet all four required criteria—co-authored by Donna Schlachter and V.A./V. McKevitt, issued as part of a named series. 1. No listings on Amazon, WorldCat, Goodreads, publisher catalogues, or author websites show any joint titles by Schlachter and McKevitt. 2. Every series entry attributed to Donna Schlachter (e.g., Christmas Mail-Order Angels, Prairie Rose, Oregon Trail, Independence Islands) is either solo-authored or co-written with other collaborators, none of whom are V.A. or V. McKevitt. 3. Searches for “V.A. McKevitt” or “V. McKevitt” return no published fiction—only an unrelated academic cited on ecological studies. Because no qualifying books exist, the answer is that there are zero such novels. ## References 1. Amazon author pages for Donna Schlachter (https://www.amazon.com/stores/Donna-Schlachter/author/B004VTKGP2) and search results for “V.A. McKevitt” (accessed 11 Apr 2026). 2. WorldCat advanced search for “Schlachter, Donna” AND “McKevitt” (accessed 11 Apr 2026). 3. Goodreads search for “V. McKevitt” (accessed 11 Apr 2026).
