Through the course of this trilogy, Monk has thrown around surprises and twists like beads at Mardi Gras. The ending of the previous book, Infinity Bell, was a perfect example. She took the world and the characters that we've grown comfortable with, and completely turned it all upside down. Crucible Zero begins with that new, unsettled world and the characters that inhabit it.
When Matilda Case attempted to mend the break in time created from the Wings of Mercury Experiment, she was successful in some aspects, others not so much. While time may have been kind of/sort of/ mended, the consequences of meddling with the experiment still caused death and destruction. Maybe not the thousands that were ultimately predicted, which is one of the areas that was a success, but the deaths that did occur were more personally devastating than losing thousands of strangers.
We find Tilly in a new time way; not her own, not the future, but an alternate period where things are the same, yet different. Everything she knows has a quiet echo of things she knew, but they aren't the same. The people she's grown to love are around, the ones she's always known and loved are present, but each and every person that Matilda has known is different. A really interesting element that became one of my favorite parts of this book was seeing previously beloved characters in such a different capacity. Some of them retained the qualities that were unique to them, others are completely different than the ones I've grown to know, and still others are the same...yet still "off". Like Matilda, I got to know each and every important character all over again.
Crucible Zero once again has Matilda trying to save the world. Even though it's been done in the previous book, it's a new and fresh scenario because the period of time isn't the same as with the other end of the world storyline. But the machinations and the foes are the same. Tilly's, and the galvanized, enemy is still around, campaigning for world domination. Only this time around, his campaign involves mass bombings of innocents. Matilda is also experiencing another hitch in her already unstable journey -- something or someone is able to remotely send her into a different time way, taking her out of the present and communicating with her in yet another alternate time. What she learns during those episodes is both frightening, yet enlightening all at once.
With Crucible Zero bringing an end to this trilogy, I can say I'm happy with the way things were resolved. I learned some revelations about characters, things that were previously alluded to, but I'm also a bit sad that things have come to an end. I do have hope that Monk will maybe (hopefully) return to this world in a spin-off, much like she did with her Allie Beckstrom series, because there is one little detail that wasn't resolved. I'm hoping that Monk does return to this world in the future because I really am itching to know the significance of said loose thread.
All told, the House Immortal trilogy has quickly become one of my favorites, one I will definitely re-read in the future. I strongly recommend this book and series for both fans of sci-fi and urban fantasy, and those who are looking for a new and fresh tale involving time travel and Frankenstein-ish creations.
