A \ensuremathθ term, which couples to topological charge, is added to the lattice CP^N\ensuremath-1 model. The strong-coupling character expansion is developed. The series for the free energy and mass gap are, respectively, computed to tenth order and fourth order. Several features of the strong-coupling analysis emerge. One is the loss of superconfinement. Another is that, in the intermediate coupling constant region, there are indications of a transition to a deconfining phase when \ensuremathθ is sufficiently large. The transition is like the one which has been observed in Monte Carlo simulations of a similar lattice CP^N\ensuremath-1 action.
