At the end of the last chapter, things were in a pretty bad way.
You’d added Mercury Meals’ code into Orion’s Orbits and were
all set to demo things to the CFO when you hit a problem. Well,
actually three problems—and that adds up to one big mess...

Your system freezes
when you try and
run it...it just stops
doing anything.
Orion’s Orbits is NOT working.
Your customer added three new user stories that relied on some
new code from Mercury Meals. Everything looked good, the
board was balanced and you completed the integration work
when, BOOM!, you ran your code and absolutely nothing
happened. The application just froze...

You have a LOT of ugly new code.
When you dug into the Mercury Meals code,
you found a ton of problems. What’s causing
the problems in Orion’s Orbits, and where
should you start looking?
You have THREE user stories that rely on
your code working.
All of this would be bad enough, but there are three user
