LORD JOHN AND THE BROTHERHOOD OF THE BLADE
Set in 18th-century Britain, the second mystery in Gabaldon's Outlander series spinoff featuring Lord John Grey has meticulously researched historical detail and an appearance or two by Jamie Fraser from the Outlander series. Not only is this a solid mystery, it also adds pieces to the Outlander chronicles, making it a great way to bide your time until the next book appears.
His quest leads to old friends, a countess's funeral and a meeting with Jamie Fraser, who knows something of the past and a bit of the future. John won't give up until he uncovers the truth. (Delacorte, Sep., 470 pp., $25.00)
