“A rollicking romp through the tropes of the cozy sub-genre fronted by a gay main character – Hayden McCall – and his clique of diverse sidekicks. Readers will be having so much fun following this gang’s escapades they will forget how radical the pairing of the gay male experience and the typically conservative cozy style truly is.”
— Kristopher Zgorski, The BOLO Books Review
