With the word Trilogy, made me think I was getting all 3
Arrival was great and on time. Thought I was getting the timepiece the second in trilogy. But will keep it and order the other two of the series I typed in the name “Timepiece” and got The Christmas Box, thinking I was possibly getting all 3. I guess that is my mistake
