The Fall is All There Is by C.M. Caplan

All Petre Mercy wanted was a good old-fashioned dramatic exit from his life as a prince. But it’s been five years since he fled home on a cyborg horse. Now the King – his Dad – is dead – and Petre has to decide which heir to pledge his thyroid-powered sword to.

As the youngest in a set of quadruplets, he’s all too aware that the line of succession is murky. His siblings are on the precipice of power grabs, and each of them want him to pick their side.

If Petre has any hope of preventing civil war, he’ll have to avoid one sibling who wants to take him hostage, win back another’s trust after years of rivalry and resentment, and get an audience with a sister he’s been avoiding for five years.

Before he knows it, he’s plunged himself into a web of intrigue and a world of strange, unnatural inventions just to get to her doorstep.

Family reunions can be a special form of torture.
