Most good stories start with a fundamental list of ingredients: the initial situation, conflict, complication, climax, suspense, denouement, and conclusion. Great writers sometimes shake up the recipe and add some spice.
Exposition
Interview With a (Very Bored) Vampire
Nina's life as a vampire is totally boring. The vampire infection makes her feel weak and sick, so all she really has the energy to do is go to the Reformed Vampire Support Group every Tuesday night. Otherwise, she writes fiction and secretly crushes on fellow vamp Dave. This set-up tells us what we need to know about her life (basically, it's the pits) in order to give a sense of where the plot can go. From where Nina's sitting (or lying down, as the case may be), things can only get more interesting.
Rising Action
One Vampire Slayer, Coming Right Up
Nobody in Nina's support group likes Casimir, the vamp who came to Australia and infected them all—but nobody really wants to see him get slain, either. Which is totally what happens. Nina and the rest of the vamps all go into hiding until they can figure out what to do about the fact that someone knows about their existence and knows how to kill them.
Worried about sliding farther into the apathetic vampiric existence that got Casimir killed, Nina volunteers to go on a road trip with Dave and Father Ramon to follow a clue found at the site: a silver bullet. We're calling this part the plot's conflict because, um, death = conflict, and also because we see Nina responding to the complications it creates. Our girl is officially out and about in the world.
Climax
Watch Out for Werewolf Wranglers
Nina, Dave, and Father Ramon run into the McKinnons, an unsavory father-son pair that runs an illegal werewolf fighting ring. They rescue Reuben, a captive werewolf, and head back to Sydney, but the McKinnons come after them. The McKinnons try to kill Father Ramon and Nefley—who turns out to be the one who killed Casimir—but instead, Nina and her pals take the McKinnons into custody. They rescue Reuben, but in a moment of chaos, Horace bites Dermid McKinnon. You win some, you lose some, right?
Falling Action
One Vamp, Two Vamp
Dermid McKinnon begins to transform into a vampire… and then bites his father, Barry McKinnon. Now the McKinnons are so debilitated from the transformation that they're no longer a threat to Reuben or Nina and her crew. Between being victimized by the McKinnons and coddled by Nina's mom, Nefley has a change of heart and decides to repent for killing Casimir by becoming the remaining vampires' ally.
During the crisis, Nina lets on that she doesn't think all vampires are awful, which leads Dave to (finally) kiss her. All this stuff happens right after the climax (with its biting and gun-waving and threatening), which makes it the falling action.
Resolution
Bloodsucker Blues
Nina and Dave are less unhappy in general, now that they've become an item. Horace is imprisoned as punishment, while Dermid and Barry join the Reformed Vampire Support Group, where they whine a lot and aren't a threat to anyone anymore. Reuben's working to reintegrate into society, and Nefley's an enthusiastic vamp supporter.
As for Nina, she declares her intention to write a book about what vampires are really like, starting with her own life, which causes a stir among the other vamps. But seeing as the plot's main threats are wrapped up—think: the mystery around Casimir's death, who mysteriously killed Casimir? What's up with the silver bullet at the crime scene? When will Nina get over being so mopey?—we're pretty satisfied to call this part the resolution.
