Well... I automatically chose 'A Treacherous Curse,' but all of the books sound interesting enough that I'm wanting to add them to my own TBR. Happy reading!
I personally like this series (Veronica Speedwell), more than the Lady Julia Gray series. The writing is just as excellent, but I couldn't stand the main male character.
Even though I didn´t like the first book in her other series (the Lady Julia series?), I might check this series out for myself.
