You can start reading Tabatha Kiss at any series.
Some series can be read as stand-alones in any order but I recommend starting a series from the beginning and following the Character Map from there.

The Snake Eyes Series

Heart-pounding romances. Interconnecting suspense stories. One unforgettable adventure!
Series without cliffhangers. For best experience, read in order.
