We find the Goldstino action descending from the N = 1 Goldstone-Maxwell superfield action associated with the spontaneous partial supersymmetry breaking, N = 2 to N = 1, in superspace. The new Goldstino action has higher (second-order) spacetime derivatives, while it can be most compactly described as a solution to the simple recursive relation. Our action seems to be related to the standard (having only the first-order derivatives) Akulov-Volkov action for Goldstino via a field redefinition.
