Broken (Armstrong novel)
Broken is a fantasy novel by written by Kelley Armstrong. It is the sixth in her "Women of the Otherworld" series and has the return of Elena Michaels as narrator. Plot summary. In this story the half-demon Xavier calls in a favour - steal Jack the Ripper's From Hell letter away from a Toronto collector who had himself stolen it from the British police files. It seems simple, but in the process Elena accidentally triggers a spell placed on the letter which opens a portal into the nether regions of Victorian London. With thieving vampires, killer  rats and unstoppable zombies on the loose, Elena and the Pack must find a way to close the portal before it is too late. To add to the confusion, Elena herself is pregnant with Clay's child (actually twins). The story begins with Elena worrying about her current pregnancy. She has concerns about what effect her werewolf nature will have on the unborn child, something with no recorded precedent in Pack knowledge. Clay and Jeremy, also concerned, have imposed a number of restrictions on her actions too, which Elena accepts but is also frustrated by. She is, therefore, not entirely  displeased to hear from Xavier Reese who offers her a deal: he will hand over information about a rogue mutt the Pack have been seeking in exchange for the Pack's help in stealing an artefact from a sorcerer - the From Hell letter. The deal is agreed to and, after the mutt has been dealt with, Jeremy steals the letter. As they leave, however, Clay squashes a mosquito and smears Elena's blood on the document. This activates an inter-dimensional portal, which releases individuals previously entrapped there during the Victorian era. Now zombies, these track Elena, putting her and  her unborn offspring at risk. Attempting to rescue her, the Pack kill these zombies, but to their shock they keep returning. In addition, cholera has infected the Toronto water-supply and the city's rats have become diseased and aggressive. Modern individuals disappear through the portal by accident, whilst murders take place that lead them to suspect that they have released Jack the Ripper himself upon an unsuspecting public.
