I have just finished Wolves of the Calla. I found the story within a story of Callahan's vampire tales chilling & exciting. I have a feeling the next instalment Songs of Susannah may refer to Salem's Lot further... Would I be best advised to read Salem's Lot before moving on to DT SoS? I know Sai King naturally weaves some of his tales & characters over & through his books but I would prefer to know no more about Salem's Lot from the Ka-tet but from Sai King himself. So do or do i not read Salem's Lot first??
