Dark Widow’s Secret by I. T. Lucas

Vivian and her daughter share a powerful telepathic connection, so when Ella can’t be reached by conventional or psychic means, her mother fears the worst.
Help arrives from an unexpected source when Vivian gets a call from the young doctor she met at a psychic convention. Turns out Julian belongs to a private organization specializing in retrieving missing girls.
As Julian’s clan mobilizes its considerable resources to rescue the daughter, Magnus is charged with keeping the gorgeous young mother safe.
Worry for Ella and the secrets Vivian and Magnus keep from each other should be enough to prevent the sparks of attraction from kindling a blaze of desire. Except, these pesky sparks have a mind of their own.
