Here's a book I plan to get for some late summer reading --

an excerpt from the review (by John Powers)
Like all of all of Marías' work,
The Infatuations is
unsettling, even slightly sinister, because it confronts us with
thoughts we'd rather not hear: that morality is provisional and can be
corrupted by many things, including love; that to survive, we invariably
start forgetting the lost loved ones whose memory we once clung to — if
the murdered Miguel returned, Luisa might actually find his presence
inconvenient. Most unsettling of all, Marías suggests that our self,
this thing we call "I," is not something solid and immutable. Like our
narrator, we cobble ourselves together from moment to moment out of
malleable memories, stories we've heard and fictions we tell ourselves
to impose meaning on what's going on around us.
