From publisher's website:
You, as Nancy Drew, must stop a bomber from ruining the Redondo Spa clients’ rejuvenation and relaxation. The high maintenance clients won’t be happy if they find that their retreat is about to explode, even if the bombs are more prankster gross-outs than dangerous.
Now, Nancy Drew is undercover as the spa gopher catering to the customers’ eccentric requests while defusing bombs. From celebrities who escape here to the receptionist at the front desk - everyone is a suspect! Who is sabotaging the spa and can Nancy catch the culprit before the spa loses all of its clients in Nancy Drew Dossier: Resorting to Danger?
