Perfect for you if...

You enjoy thrillers with paranormal twists that don't bog down the pace with mythology explanations.
You want a strong female duo with chemistry and actual competence, not just quippy banter.
You're looking for fast-paced plots where the stakes escalate quickly and personal danger forces characters to level up.

Maybe not for you if...

You prefer standalone books with neat resolutions, since this is book one of a series with threads that won't wrap up.
You want deep character backstory and emotional arcs; this one prioritises plot momentum and mystery over introspection.
You're after paranormal romance; the focus here is on danger and conspiracy, not relationships.

About this book

Jazz Callender, a disgraced former detective, receives an unexpected offer: funding to start a private investigation agency. The catch is partnering with Lucia Garza, described as a national security risk, accepting one hundred thousand dollars, and taking on assignments with unclear purposes. When Jazz is shot and one of their surveillance subjects dies, the partnership becomes urgent. As they search for answers about their mysterious employer, Jazz and Lucia discover they are pawns in a psychic game with stakes extending far beyond their own futures. This is the first book in the Red Letter Days series.
