Like low-fat ice cream, linked-story novels are an invitation to disappointment.

Often, they're satisfying neither as novels nor as story collections, but Julia Phillips' debut, "Disappearing Earth," is an exception. The individual stories are sharp portraits that add up to something deeply rewarding. Stretching from August to the following July, the book's opener fills you with dread the minute sisters Sophia and Alyona spot a man on the deserted beach where they're playing. From talking to him to accepting a ride, the sisters make a series of bad decisions that reverberate throughout the town of Petropavlovsk-Kamchatsky.

Phillips' bleak depiction of that Russian city sets the stage for her riveting debut. It's on the peninsula of Kamchatka, which seems to be an easy place to vanish. On the eastern edge of Russia, closer to Alaska and Japan than to the rest of Europe, it's described as almost like an island because a mountain range and an active volcano isolate it from the rest of Russia. Phillips makes Kamchatka seem ordinary in the way people go about their lives but otherworldly in its residents' calm acceptance of tragedy (one chilling plot point is the years-earlier disappearance of another girl, who is considered a runaway despite evidence to the contrary).

Each story in "Earth" introduces a new plot and characters, one of whom always turns out to be investigating the sisters' disappearance, or related to the missing girls or obsessed by a theory about what became of them. It takes a while to vibe with these resets, especially since about half of the people have names that begin with the letter "A," but "Earth" spirits us along because each new set of characters turns out to be so compelling.

There's Oksana, who ends a long friendship when her distracted pals lose her dog. And brash Valentina, so fearful about the girls' disappearance that she clamps down on her own daughter, forbidding her to see her best friend. Valentina behaves appallingly, but she's humanized by the revealing detail of a blister she has ignored for a year. It's as if the bandage she covers it with is holding together Valentina's entire fragile existence, because bad things happen as soon as she goes to the doctor.

"This was exactly what she had feared — she allowed one disruption, a bandage removed, and her whole life crumbled after," Phillips writes, the simplicity of the sentence contrasting with how precisely it nails human frailty.

Many of the characters in "Disappearing Earth" cling to similar magical thinking, and it's unclear whether the man who believes his sibling was spirited off by aliens is any less realistic than the mother who thinks it's possible to cloister her daughter from harm. As each succeeding story of "Disappearing Earth" takes us another month away from hope that Sophia and Alyona will be found alive, it becomes apparent that the book is not about the sisters but about a place so remote and unfriendly that it only takes a couple of months for a tragedy to become a dark fairy tale the characters tell one another.

Phillips' writing is spare but canny. The first story, for instance, gives us more information about what happens to the sisters than anyone in the book has, establishing a kind of complicity. "Why are you not following up this lead? Why are you not asking that question?" we want to shout at the characters, who seem to forget the sisters even as the vividness of that first story assures that we can't.

Phillips' work reminded me of Dan Chaon's "Await Your Reply" and "Ill Will," beautifully written fiction that might be called a thriller if it weren't so clear that none of the devastated characters is the least bit thrilled.
