This is a young adult/children's book read some time around 2004, in English. Unfortunately no recollection of the cover. Remembered details are:
- a boy is on vacation, or perhaps has moved, in a hot, dusty place
- there is abandoned house
- the boy befriends another child (could also have been an old man with a youthful spirit)
- time jumps to when the house was not abandoned
- a scene with an inexplicable wind inside the house
- a scarab beetle was important, in some way
- I think the book ended with a scarab beetle scuttling in the sand.
Which book is this?
