Dark Autumn (Book 2 of the Caelli Rivers series)

When two skeletons are uncovered, seperated by decades but connected to one man, Caelli Rivers knows that something is a little hinky. When more deaths are discovered, Caelli knows something is definitely wrong. Digging through the past, rumours about a old European family steeped in bloody deaths and suspicious disappearances begin surface and it all started with the death of Nicolas Flamel.
