The Itinerary, livre audio

When Lisa’s dad passed away, she and her mom planned a European vacation as something to look forward to in their time of grief. With her mom's untimely death just weeks before the trip, Lisa decides to embark on the non-refundable journey on her own, armed with her mom's bare-bones itinerary and well-loved copy of Bob Adams' Adventures.
